I used to have some more of these Akro “Lemon Drops”—I am darned if I can find them. Cool marbles, not a slag or a corkscrew—not a swirl—just an Akro---something. This is a weak one at 23/32”. They came bigger for sure.
A bit of white with lots of yellow, they look like they should light up under UV—the yellow glows orange on this one.
Marble—On!!
