Vintage Capsela Construction Set / Parts from 1980’s. S.T.E.M.

No box or instruction manual. Lots of parts all untested so consider this an as is sale. Not sure what set this is or whether or not it’s complete so look carefully at the pictures. The only thing I noticed is that one of the red wires is broken at one end but I may have missed something. New to Poshmark? Sign up with my code - bethsava - to save $15 on your first order!
