Vintage M.U.S.C.L.E. Men Figures Muscle men glow in dark Mini Charms Rare KO

Incredibly rare lot of miniature muscle men that glow in the dark and have loops for charms. Could only find 2 other posts of them on the internet with no info on origin. I do not think they are bootleg, they are the actual m.u.s.c.l.e. characters
