Battleship travel Kit Card

Available as a multicolor print for ams (or other multicolor systems) and as a single color.

10x2mm magnets are required and all pieces can be stored inside while closed (altough you might want to carry a small bag if you don't want to tidy up). In the event magnets are shorter than 2mm (happens quite often) you can always add helper disks of 9.8mm diameter and 0.2 or 0.4 mm tall.

If top layer is not smooth, a gentle touch of sandpaper and torch comes quite handy.
