Review: So Pretty--and They Work! - I love these! They're so pretty, and I like how each size is a different color because it makes it really easy to find the correct size. I have made so many booklets with these! It says they are plastic; however, I think there's a little metal that lines the plastic. Anyway, when you are finishing the booklet, you can clip and bend the ends of the coil. I am very happy with the booklets that I've made with these coils!

## Questions & Answers

**Q: How many pages will the 3/4 fit? using tgtb curriculum.**
A: The 3/4 inch coil will hold about 170 sheets.

**Q: Will the 3/4" coil fit a 1" thick book? (specifically a whole tgatb language arts and math book)**
A: I do not think it will.  I think you will need an inch and half coil. This will give you enough space so the pages will turn. hope this helps.

**Q: What binder machine works best with these spines?**
A: 4:1 Pitch: spiral binding spines fit letter size paper (8.5 x 11.0 inches), the binding spirals have a 4:1 pitch, will fit any binding machine that punches 4 holes per inch.

**Q: Can I use these with the holes the Cinch makes?!**
A: I would not think so.  These coils are designed for 4 holes per inch.  I looked online and found the Cinch punch makes 2 holes per inch. If you want to experiment and try, I would recommend getting a single coil to try.
