More floating keychains?
Seems popular! Here's another set of 5 floating classic keychains. A pretty stiff foam is encased in a squeezy-softer rubbery coating to make these keychains. If dropped in the water, a set of keys would float using these. Each one is a different fun shape, too. The first orange one has Knuckles & the logo as line art & reversed as solid art with a lightening bolt shape dividing the two. The Tails foam is yellow with his face in a lightening bolt-ring & the logo in a banner at the bottom.

The center is a solo Sonic blue one with several sihloutte/stripe & solid echo-shapes for him, and the logo in a little rectangle. The triangle keychain features solid Sonic & line-art Amy with a logo as a banner across them. The somewhat egg-shaped all black keychain (would please Eggman, no doubt) has a nice Eggman art in a gear shape, with a rectangle banner logo. This set is especially nice, because the characters get solo treatment / a keychain of their own. Eggman fans would never pass up his, & the Knuckles one is great too. The creative use of the stock art keeps these looking fresh, even today!
