Chumia 100 Pcs Twin Loop Wire Binding Spines Spiral Binding Coils Metal Double Loop Wire Spines Combs 1/4in 5/16in 3/8in 1/2in 9/16in for Teacher Student Document Notebook Making(Colorful)

Used with Fellowes E-Wire binder. Easy to use. As described. Each size is a different color. Packed wrapped by size making it easy to determine what size each color is. Don’t rush separating them or they will tangle.

I was worried I would get this and they would all be the same size but they were a nice variety.

They work well but they are not 12 inch long. They r 10 inch long. It created a headache for binding a standard 8.5 by 11 book of paper.

I bought these coils for the WR Memory Keeper cinch and it did not work for it! The quality is not best.

Muy mala calidad

These have worked very well. That being said it's frustrating not having the sizes labeled. Especially for someone new to using this type of binding. Otherwise I'd definitely buy again.

The wires themselves are on the thin side. I didn’t care for all the bigger wire binding being one color, all the medium being another color… if the colors would have been distributed more to the different sizes, I would have given a higher star.My other objection is that I can only use the green and blue wires without over stretching them to fit. I feel the smallest size can still work but it’s harder to work with when using a cinch.

Do not buy these if you are wanting to use them for a cinch as they do not work. I emailed customer service with no answer.
