Because it is allergy-friendly, those with sensitive skin can use it with peace of mind, as it will 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. ◆ The Japanese Ryukyu Hotaru Glass is handmade by artisans one by one, so no two are exactly alike.
