Surgical Stainless Steel Medical ID Plaque with Severe Food Allergies pre-engraved. Fits on any of our interchangeable sport straps or faux leather straps. Can be purchased separately. Made of 316L Surgical Stainless Steel. Most medical bracelets on the internet are usually 304 Stainless. Although both are hypoallergenic 316L is non-corrosive. You can choose between traditional (etched) style engraving or black/lasered engraving for this item when you select your font. There is no color added in traditional engraving. We simply etch the inscription into the metal in the font selected. For black/lasered style engraving, the inscription is lasered onto the metal in black letters using either a Plain Block font or Block Fifth Avenue font. (Front pre-engraved with Laser)
