HOUYEE50 Pack Plastic Spiral Binding Coils, 20mm(3/4"),170 Sheet Capacity,4:1 Pitch (Black)

These work really well and are a great way to have multiple colors without having to have 100 of each color. It's a great money saver.

I have a cincher and make my own books and journals. Usually I hand sew them using a coptic stich but at times when my hands are being difficult, I’d rather do a spiral and these are perfect! They are the 3:1 size so make sure thats what you need. Same in several circumfrences so I have a choice how thick a book I want to make. Now I need these in some cool colors! :)

What a great deal on a huge box of spiral binding! I used them to bind materials for my classroom but you could also use them in other professional settings. They are easy to insert and crimp. I would say these are probably medium sized. They are great!

Works. What can I say.

I was hesitant to order because they were a good price, but they worked and seemed just the same as the others we've gotten before. Thanks for the value!

Very easy to use when binding a book!

I liked that it came with the pliers. Happy surprise, but I have two pliers now.

I bought this brand because the vendor had all sizes in in. on one page, not a different size in cm on all different pages. I found them to be thinner and much more flexible than the Trubind brand. They worked, but were too flexible to be driven through the holes automatically by the spinning rubber wheel. I manually twisted the coils through about six books. The size I had of the Trubind coils twisted into the holes perfectly.

J’ai acheté ces spirales comme jouets pour mes chats. Étant donné que ceux en animalerie coûtent plus cher et que mes chats finissent par les perdres sous les électroménagers, cela revient avantageux comme achat. Donc je ne suis pas obligé de tasser les électroménagers au 2 jours. Je leur en sors de nouveaux
