This is allergy-friendly, 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 material is rust-resistant and less likely to discolor, making it easy to care for. It is also easy to remove dirt, and is very convenient for those who do not have allergies. ◆ Japanese Ryukyu Hotaru Glass is handmade by artisans one by one, so no two are exactly alike. There may be slight imperfections.
