These educational coasters are made of HDF from Germany, It is heat resistant and fairly scratch resistant. Surface will save the table top from the hot cup bottoms. 4 constellations are engraved on each coaster, which have the exact location of Alfa, Beta & Gama stars along with the other stars scattered in the constellation. Stars are connected with lines to make the widely recognized shapes of those constellations. You can see the main stars sparkle against the light source as they’re cut into the coaster.
