Rayson WR21159BK Wire Binding Spines, 2:1 Pitch Double Loop Binding Wires 5/8 Inch, 21-Loop Wire Ring Pack of 50 with Black

These are very good quality, very strong, work great, just thr right size for my training manuals. I would buy these again.

This product was nice and firm. I had ordered from another company before ordering these, but I quickly found out that this brand is much more sturdy

Not much to say when it comes to wire spines. These have a nice coating that doesn't break when you bend them and them bend nice and easy. They are one of the best prices per spine too, so worth buying.

Encantada me encantó. Son de buena calidad trae muchos anillos y por el precio excelente

They are fine binding coils, good quality. Only problem I have is that they only have 21 "rings", but when I punch holes in a 8.5x11 sheet of paper (the 11" side), there are 22 holes made. So inevitably, there's a hole either at the top or the bottom where the binding coils doesn't reach. It's fine for personal projects where looks don't matter, or with anything smaller in size than 11".

I ordered wrong size, but nice product

These arrive in a white box, and while it keeps them together with all the moving around during transport some of these had to be cut away from the others due to being tangled. I use these to create my own stationery so it was a little frustrating to have to lose a few but overall the value of this product is great! Very sturdy!

Easy to apply, making putting books together easy. Comes in different sizes to accommodate any size book
