These eyelets are grooved and come with an o-ring, and are made of 316LVM ASTM F-138 implant grade stainless steel with a diamond-like carbon coating. They've been discontinued by Industrial Strength and we will not be ordering anymore, so whatever choices in stock are the only options.
This item will have either clear or black o-rings, depending upon what the manufacturer uses. We have no control over this. If you want a particular color o-rings , be sure to get them separately.
