I have had bioflex in my nipples since they were pieces about 11 years ago. With that being said, plastic does melt, but these are not plastic, and who is microwaving their nipples to see if the rings melt?! These rings are a very comfortable fit. Also they do glow, but only after being charged in light. Some have balls that glow, others just have bars that glow, keep that in mind. The bars have ample room for those who need it, but not so much room that those of us on the smaller end of the scale have troubles with excess length. Keep in mind that these do not come in matching pairs, but 10 different colors, so if you want pairs, order two (which I'll be doing). Very worth the value, cute and comfortable!

These look exactly as pictured with vibrant colors. They are easy to put on and take off and are quite comfortable. I have no complaints and would definitely purchase these again.

Very cute.

Fits perfect. Glow great. Love them. Perfect for nipple ring

Came on time and really glow in the dark for about a half hour as long as you put it under the light first

Don’t actually glow in the dark I’m upset thanks a lot

Nice just as described!

Exactly as described.

They don't even glow in the dark. Waste of 10$. So disappointed. If I could give no stars. I would.
