Round coffee/drink coaster stand/holder. Features slots at the bottom for bumpers/feet, or you can attach a cork base, etc.

About 110mm x 30mm. Can hold coasters with a diameter of up to 100mm.

If used with my own coasters, it can hold up to 5 without the optional feet, probably 3-4 with feet depending on their height.

It should be pretty easy to adjust the height if you need to hold more or fewer coasters, or depending on the size of the coasters.
