I created coasters with Super Heros Logos.

Fore some coasters a 0.2mm Nozzel might be the better option.

The size is 100 x 100 mm and 4mm thik. I added a 1mm cork Layer on the back of the coaster.

Thanks to the cork, the coaster on the table is not quite as slippery.

I bought 1mm cork tiles on Amazon.

These are the tiles I bought, they are Self-Adhesive.

Here you will find the coaster holder.
