Coasters 60s 70s space age

Set of 6 coasters straight out of the 60s or 70s with this orange color typical of this era and these patterns in the shape of planetary rings which are characteristic of the “space age” period. They are made of a kind of acrylic resin (plexiglass?) which is very hard, very transparent, you could think of it as glass, minus the fragility! The patterns are incorporated into the resin and will therefore not fade with washing. They are in good condition, little or not used, the bottom is very clean, just tiny marks of use but they have some small original defects: an incomplete orange ring on one, an air bubble in another and a few slight small “hollows” on the surface of some, invisible unless the light is projected at a very precise angle (air bubbles at the time of pouring the resin most likely). They measure approximately 9 cm in diameter, with a thickness of approximately 7 mm.
