Wow, I thought they were metal until I read the comments, as well. Such killer detail for woodwork, and it's fantastic they've held up so well after 30 years. I'm sure they will bring you joy for many years to come! I never learned how to play chess but perhaps someday I'll have the patience to give it a try!
You should give it a try it is lots of fun :D
Thank you for stopping by! :)
