Kaos Silver Silicone Hydra Eyelets are made with the highest quality implant grade silicone and manufactured in the USA. These have a slight teardrop shape. This pair comes in sizes 00G gauge up to 1" with a 8mm (5/16") wearable surface from 00G to 1 inch. Soft and squishy, they can be washed with a mild non scented antibacterial soap and water. These are slightly thicker than the skin eyelets but still flexible. Note: these are not suitable for ear stretching.
