Description
For hot beverages I would recommend PETG. A really hot cup of tea or coffee may make a very shallow but visible mark on the top pattern if the coasters are made of PLA like the ones in the picture.
The filament color is Prusament Army Green: https://www.prusa3d.com/product/prusament-pla-army-green-1kg/
