This is hypoallergenic, so even those with sensitive skin can use it with peace of mind, as it won't cause swelling, itching, rashes, or redness. ※ Individual results may vary. Surgical stainless steel is rust-resistant and less likely to discolor, making it easy to care for. It's also easy to remove dirt, and is very convenient for those who don't have allergies as well. ◆ Japanese Ryukyu Hotaru Glass is handmade by artisans one by one, so no two are exactly alike. There may be slight imperfections.
