This is a set of Kyoshin Elle genuine leather slipper kits. Includes simple instructions and design patterns. You'll need a grommet punch (for finishing and making holes) and stamps if you want to add patterns, but with just those tools, you can make leather slippers. Finished outer dimensions (approximate): Length 26 cm, Width 10.5 cm This kit has been stored at home for quite a while, but it's in good condition with no leather discoloration because it was stored in a dark place. There are a few stains on the felt.
