Etrnal Rings I have been very happy with my purchase of the Etrnal silicon ring. The website is easy to navigate and returns/exchanges process is quick, simple, and free. The ring pricing is affordable. I have sized wrong twice now and it has been no dramas swapping them over. I would highly recommend printing off the measuring strip from the website and using it to size up the ring. It was simple and alot more effective and accurate than measuring it myself with a measuring tape and matching it to the size chart (what I tried the first two times) The rings that arrived have been of good quality, colour, and strength. I will be recommending this product to others looking for silicon rings.
