Binditek 100 Pack Plastic Spiral Binding Coils, Multi Size (6mm, 8mm, 10mm, 12mm) (1/4", 5/16", 3/8", 1/2"), 4:1 Pitch, Black, for Students and Coworkers

Quality made. No issues using them. Perfect product.

Item arrived when promised. Easy to use. Unboxing easy and effortless. Would purchase again from seller.

Most coil binders use 4:1 - these are perfect for those machines that only use 3:1 coils. Well priced.

I got them because i had a 130 page book I wanted to spiral-bind that was right on the edge of 5/16 the biggest twin loop coil it can take. The largest coils in this pack worked great for spiral binding the book with plenty of space for turning pages easily. The multi-size pack is awesome, and I would definitely buy it again.

The dividers were the quality I expected. The white tab inserts came in single columns of detachable tabs which is fine I I wanted to hand-write the labels. I would prefer to have the insert tabs all on one sheet so that I can put them through a printer.

The product is working great for binding songbooks for our nursing home services. The coils seem to be sturdy and I expect they will last a long time. I appreciated the option to purchase one size only or a variety of sizes in one box. I also liked the variety of sizes and colors available.

I returned these because I bought the wrong size, BUT they were great quality and a great price for how many you get.

I really didn't need this it is just an impulse buy, but it works great, smooth cut.

Medida correcta , llego antes de lo esperado , muy buena calidad , piezas completas

I got these to make my little brother some handy dandy notebooks like in blue's clues and he loves that they have a red spiral just like blue's! We've used the other colours to make other themed ones as well

Works well

Work well on the binding machine but they aren’t great for bending at the ends (lots of breakage) so leave extra ‘room’ as you bend!
