One of the best things about this product is that the girth of the rings isn't set- in other words if you need to get them off you can. I love that there is a variety of different textures and sizes of rings. Whether you want a little something extra, or a lot- this set will cover it all. The spiked ring looks a bit intimidating but the material that all of the rings are made of is soft and stretchy. All rings worked well, felt great and didn't break!
