As it is allergy-friendly, it can be used with peace of mind by those with sensitive skin, as it does not cause swelling, itching, rashes, or redness. ※ Individual differences apply. Surgical stainless steel material is rust-resistant and does not easily 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.
