20,000 pieces Rubber O-Rings OD 8MM ID 6MM Purple Le Joint Francais - Hutchinson
I do not know what the rubber material is, might be silicone. Made by Hutchinson Seal in Mexico for Le Joint Francais. I do not know what devices these are used in. New bag of 20,000 pcs!
Use in arts and crafts, or jewelry or industrial use. Original cost was probably insane!
