Artist's commentary
Hang in There, Kogasa-san 3335
The ring sleeves for crimping come in four sizes: ○, S, M, and L. Figuring it'd be best to have a crimper I could use all the way up to size L, I bought that, and this is the result. Since the test only uses sizes up to M, I realized I should've bought one a size smaller for use on up to M.
Despite how I've titled the strip, the tool doesn't open if you don't squeeze properly, and you don't pass the test if you don't install the ring sleeves as stipulated, so it's no problem.
