End-tab vs. top-tab — what’s the difference?

End-tab folders show the tab on the long side and are used on open-shelf systems; top-tab folders show the tab along the top edge and are designed for drawer filing.

When should I choose classification folders?

Choose classification folders when you need built-in dividers and 2-prong fasteners to separate sections within one file—ideal for medical charts, legal matters, and case files.

Letter or legal size — how do I pick?

Letter (8.5\" × 11\") fits standard documents; legal (8.5\" × 14\") fits longer forms. Match the folder to both your documents and storage equipment.

What tab and material options are available?

Tabs include full-cut, 1/2-cut, or 1/3-cut (assorted positions). Materials range from 11-pt to 18-pt manila, with optional reinforced (2-ply) tabs for added durability.

Can I add fasteners, pockets, or expansion?

Yes—add 2\" bonded fasteners (various positions), pockets/jackets, and expansion gussets (e.g., 3/4\" to 2\"+). Check each product’s options for capacity and placement.

Do you offer volume pricing or custom printing?

We offer bulk price breaks and custom printing (logos, lines, colors). Call (800) 810-3453 for a quote.

What safety labels should I look for on school and early-childhood items?

For children’s products, look for CPSIA compliance and a Children’s Product Certificate (CPC). Art materials should be labeled to ASTM D-4236; many also carry ACMI’s “AP” (non-toxic) or “CL” seals. These help confirm proper cautionary labeling and third-party testing where required.

How do I pick classroom furniture across grade levels?

Favor adjustable-height desks/tables and seating tested to ANSI/BIFMA X6.1 for educational use. Check manufacturer grade/height charts; adjustable ranges let you cover multiple grades with one model and simplify purchasing and spares.

What’s the best way to organize supplies and centers?

Use latching, stackable bins (clear for quick ID; colors for zones/subjects). Add label holders on bins and shelves, and keep a posted color key so students can reset the room independently.

How do I choose learning games and manipulatives by age?

Match to the stated age/grade band and learning goals (fine motor, numeracy, literacy). For early childhood, prioritize oversized pieces, wipe-clean surfaces, and non-toxic finishes.

What should I consider in a charging/tech cart?

Count devices and case sizes; verify slot width/height, cable management, ventilation, and locking doors. If devices support fast-charge (e.g., USB-C PD), confirm the cart’s power specs and total charging wattage.

Do you support school POs, bulk pricing, or custom printing?

Yes—volume pricing and custom imprinting (school name, mascot, subject headers) are available. Call (800) 810-3453.

Sheet vs. roll labels — what’s the difference?

Sheet labels (letter-size) run through laser/inkjet printers; roll labels feed through thermal or dedicated label printers.

Permanent or removable adhesive?

Permanent adhesives are best for long-term filing; removable adhesives peel away cleanly from most surfaces for temporary notes or re-use.

Will these labels work in my printer?

Check each item’s spec for “laser,” “inkjet,” or “thermal.” Avoid running inkjet-only sheets through a laser printer.

How do I match the label size to folder tabs or binder spines?

Measure the printable area of your tab or spine and match to the label’s width/height. If unsure, choose a slightly smaller label for clean alignment.

Can I get preprinted sequences or color bars?

Yes—choose preprinted sets (A-Z, 0-9, months) or request custom colors/text to match your filing system.

Do you have templates?

We provide size specifications and many customers use common label templates. If you need help aligning, call (800) 810-3453.

What do 5-, 8-, 10-, or 12-tab sets mean?

That’s the number of tabs per set. More tabs provide finer organization; fewer tabs give larger, easier-to-read tabs.

Paper vs. poly — which should I choose?

Paper (often with Mylar-reinforced tabs) is economical and easy to write on; poly resists tears and moisture for heavy use and frequent handling.

Are the tabs printable?

Some tabs are hand-write only; others are laser/inkjet printable. Check each product for “printable” support and printer compatibility.

Will they fit my binder?

Choose letter (8.5\" × 11\") for most 3-ring binders or legal (8.5\" × 14\") for longer documents. Many options are pre-punched for standard rings.

Can I mix preprinted and blank tabs?

Yes—use a preprinted core set and add blank or custom tabs for sections unique to your workflow.

Do you make custom tab sets?

Yes—tab titles, colors, and sheet stock can be customized. Call (800) 810-3453.

Which paper weight and brightness should I choose?

Use 20 lb / 75 gsm, 92-brightness for everyday printing; step up to 24–28 lb and 96+ brightness for presentations and double-sided color. If you print heavy coverage or duplex often, the thicker stock helps reduce show-through. Always confirm your printer’s supported paper weights.

Round-ring vs. D-ring binders — what’s the difference?

D-ring binders hold more paper at the same spine width and keep pages lying flatter, which reduces edge wear. Round-rings are economical for smaller sets. Pick capacity based on sheet count and how often you turn pages.

What does “sheet capacity” mean on staplers and hole punches?

It’s measured using standard 20 lb copy paper. If you use heavier paper, expect a lower effective capacity. For shared spaces, choose high-capacity staplers/punches to avoid jams and downtime.

Will labels, envelopes, and mailers work with my printer?

Check each item’s spec for “laser,” “inkjet,” or “thermal.” Laser-safe adhesives resist heat; some inkjet-only sheets shouldn’t go through laser fusers. Use your printer’s label or heavy-stock setting for best feed and adhesion.

How do I choose mailers and shipping boxes?

Bubble or poly mailers are great for lightweight, non-fragile contents; corrugated boxes protect heavier or delicate items. Match interior dimensions to your contents, add cushioning if needed, and choose stronger board as weight increases.

Do you offer eco-conscious options or bulk pricing?

Many items are available with recycled content or reduced-waste packaging, and we offer volume price breaks. Call (800) 810-3453 for large-order help or product guidance.

What ball sizes should I choose for different ages?

Use age-appropriate sizes for safer, more successful play. Common guidelines include: Basketball—Size 5 (27.5\") youth, Size 6 (28.5\") intermediate, Size 7 (29.5\") official. Soccer—Size 3 up to ~8 years, Size 4 ~8–12, Size 5 ~12+. Volleyball—Regulation balls for teens/adults; lighter training balls for younger players. Always check the product page for the manufacturer’s recommended age range.

Indoor vs. outdoor — which materials hold up best?

Composite or rubber-covered balls and poly cones hold up well outdoors; leather and finer composites are best indoors. For markers, look for UV-stable plastics; for goals, choose powder-coated frames and weather-resistant nets for outdoor use.

How many pinnies, cones, or markers do I need?

For classes and drills, packs of 12 are a good start; 24–36 pieces cover full-class activities and multiple stations. Choose mixed colors for quick team splits and field zones.

Tips for storage and care?

Use ventilated ball bags or carts, wipe down gear after outdoor use, and avoid prolonged heat/sun in storage. Inflate balls to the manufacturer’s recommendations and check pressure periodically to extend lifespan.

Are items latex-free and school-safe?

Many products are offered in latex-free or phthalate-free materials. Look for those callouts on the product page. Children’s items may include compliance statements on labeling; review those details if you’re purchasing for younger ages.

Do you support bulk orders or custom printing (team names)?

Yes—volume pricing and custom imprinting are available on many items. Call (800) 810-3453 for a quote or assistance with large sets.

Do you offer free shipping?

Yes—free ground shipping on orders of $99+.

What are your shipping rates?

Labels-only orders under $40 ship for $6.95. All other orders ship for a flat $14.95.

Do you offer bulk discounts?

Yes—volume pricing is available on many items. Contact us for a quote or large-order assistance.

Do you accept purchase orders (POs)?

Yes—we accept POs from schools and government agencies. If you need terms or documentation, please reach out.
