Allergy-friendly (titanium, stainless steel) earring parts bulk sale set. (※This does not guarantee that all people will not have an allergic reaction) These parts do not discolor and are hard, making them scratch-resistant and long-lasting. I purchased a large quantity for handmade accessories, but I have some left over, so I'm selling them. The parts are sent by weight, so the number of pieces may vary. Please refer to the product images at the end for each size.
