## Description

TruBind 10mm (3/8 in.) Spiral Binding Coils for Reports, Presentations and Proposals | 4:1 Pitch | 12 in. Length | Blue | 75 Sheets Binding Capacity | 100 Pack

## Features

- QUALITY PLASTIC - Easily create bound projects that lay flat with our binding coils. Their durable plastic construction wont bend or snag, and they look great on business proposals, reports, menus, and more.
- PRECUT COILS - Each TruBind coil is 12 inches long and fits a letter-sized book, document, or binding project perfectly. Our coils have plenty of excess, so you can crimp the ends for a finished look.
- 10-MM PRE-SIZED COILS - These TruBind plastic coils measure 10mm, or 3/8 in diameter, for increased durability and holding strength. Easily bind books, documents, or reports in-office with pre-sized coils.
- BINDING CAPACITY - Our plastic coils can hold up to 75 sheets of standard 20# copy paper each when bound. That equals a maximum binding capacity of 11/32 inches in thickness, perfect for most office projects.
- 4:1 PITCH - Compatible with most 4:1 coil-binding machines, our plastic coils have 48 loops per 12-inch coil. Their 4:1 pitch matches the 4-holes-per-inch punching pattern on the side of your book.

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent product!
  

*by M***T on Reviewed in the United States on May 21, 2019*

Wonderful! Exactly as described.  I hand-spiraled these in, and they went in quickly and perfectly! They were longer than my 8.5x11 paper, but I trimmed the edge off easily. Also, I melted the edges with a stick lighter to soften the plastic and fold it in on itself so they can’t be un-spiraled (I’m a teacher and need to think of this!) and it worked perfectly! Wanted to share the suggestion. Anyway, main takeaways:1) Durable2) Easy to use3) Exactly as described4) I will definitely be ordering more!

    Better than expected
  

*by V***E on Reviewed in the United States on May 19, 2019*

The machine works wonderful. I figured I would have to punch less than 6 pages at a time. Twelve at time is easy. I have already used two 500 sheets packs of paper making up 40 page books. I missed aligned the holes only 2 times. For me that is amazing. It is easy to use and to use correctly. The spiral binders are quickly to add. My only issue is crimping the end but that is just because of a lack strength in hands.

    Love them!
  

*by B***I on Reviewed in the United States on November 26, 2019*

These work great for our preschool portfolios, class books, and homemade coloring books! We also use them in our repair shop for binding guides. Great price, easy to use, and fast shipping!
