Please choose from the images and let us know in the comments. ◆ Japanese Ryukyu Hotaru glass is handmade by artisans, so no two are exactly alike. There may be slight imperfections. ◆ All parts other than the Hotaru glass are surgical stainless steel 316L. They are hypoallergenic, so even those with sensitive skin can use them with peace of mind, as they 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 very convenient for those who don't have allergies.
