These rounds are the size of a zendala and a perfect size for tangled coasters.
They are six different kinds of wood veneer coasters [Cherry, Kiri, Indian Birch, Maharukh, Mahogany, Silky Oak] which have a gumming sheet behind which has to be removed when you want to paste it on another wood, glass or anything else you may think of. All the Sakura Microns work on it. Even watercolour pencils and paints work on it.
These wood coasters come along with the same size, six MDF wood coasters so that you can stick your tangled wood directly on it. A suggestion, spray wood varnish on the final tangled coaster to give it a finished look.
