These are perfect for our various nipple chains and dangles. The 'clear' silicon rings have been found to be much less irritating than the black rings. The bead allows for a snug fit. Jump rings are ready for our dangles and nipple chains.
The silcone rings used here are 1 1/4" which should fit over a nipple about 1/2-5/8" diameter maximum. If you need larger, leave a comment.
