Grip and cleaning-edge shapes distinguish these three tongue-cleaner designs, not an assumed metal grade. One has two slender arms with small loops at the ends, joined by a broad curved scraping section.

A second narrows through a grooved handle into a teardrop-shaped loop. The third takes a wider U-shaped outline with longer, more open arms. All three have a smooth-looking reddish-copper appearance, but that colour alone does not establish copper composition. The alternative profiles give procurement teams concrete differences to record when discussing designs.

Before selection for oral-care use, buyers should obtain confirmation of material composition, edge finish, hygiene and contact-safety requirements, actual dimensions and whether the three styles are supplied individually or as a group.
