All three have a nice glossy finish to them. The celluloid has held up well, resistant to any scratches. There are a few tiny spots where paint has rubbed off, but these were hand-painted so it may simply be that they missed a spot when painting them. There are some areas where they imprecisely painted beyond where they were supposed to, but I'm nitpicking here. These are nice, fun vintage collectible pieces.

They are not marked in any way. They are a very hard plastic that makes a distinctive clink sound when knocked into one another. If you old them up to a strong light you can see through the edges. I tried the 'smell test' to determine if these are celluloid but they did not have a recognizable odor. That simply means they were made after 1927, however, when camphor was removed from celluloid. Celluloid was especially popular in Japanese products of the 1950s so my guess is that is their origin. With so many U.S. military members stationed there, it's easy to imagine these being made to sell to the Americans.

They each weigh about 8 grams and stand a little over 2" tall.
