### ⭐⭐⭐⭐⭐ great product, staple for us for our binding machines
*by C***R on May 18, 2025*

Stock item for our binding machines, make sure you are ordering the right size coil with the right pitch, the product description will tell you, and make sure you half your book - 100 page book is 50 pages both sides, do you need a coil that comfortably holds 50 pages. we make smaller books so we cut off the excess coil with a scissor or cutting pliers. this is an excellent product, easy to use, quality is great. standard design which is what publishers want. happy publishing!

### ⭐⭐⭐⭐⭐ Great quality and variety
*by T***W on June 30, 2025*
