Japanese glass fishing float, three inches in diameter (but no obvious round number in metric...)
fairly large. Bigger than most of these black floats, anyway. I tapped a fingernail against it, and it seemed like it could be metal instead of plastic. Cold. About half-filled with water. Then I took a picture and forgot about my curiosity over its composition. I think floats are nearly all plastic, though, and it's not you care anyway, O hypothetical reader, so never mind.
Saw two today. Don't remember seeing this sort before. Maybe a little less than a foot in diameter. Those are gooseneck barnacles.
A similar float to the last (black plastic, about a foot in diameter), though it had a rim around the equator which I hadn't seen before. Here is some sort of logo.
DIA 30cm Hi-zex Float SANSHIN-KAKO CO. LTD.
A decent number of greenish floats (sometimes bearing "75 cm.") with Korean script last year. Only one this year.
UPDATE: Wandering back through at random after float season has ended, I notice my typo. But did I mean 7.5 cm or 75 mm? I meant one of those, anyway. I don't remember how they were labeled.
about a foot across. If you live in the civilized world, I think that's something like 30 cm.
