Frosted Kalo Coaster (Set of 4)
These coasters measure 4" x 4" and are made from 1/4" cast acrylic.
They just need soap and water to clean. Do not use rubbing alcohol as this will weaken the acrylic, leading it to crack.
Some of the masking tape residue may be left and will come off with normal use or soapy water. Lemon essential oil was used to rub the sticky residue from the masking that protects the acrylic when it is laser cut.
