White nylon plastic with a matte finish and slight grainy feel.
About this Product
Tea light ring (but be careful of heat - white, strong and flexible is supposed to be OK to 80 deg. C/176 deg. F).
(Scaled up a bit because I realized it wasn't going to fit around my glass tea-light holder - but the smaller one is still available.)
The snowflake is a 3D version of a snowflake in glyphomosaic.png, a file that comes with Meshlab, credited to "RANDIJROST" (I think).
