These special kits are made by Volker Arnold from Germany. Since lockdown I have offered to sell his items on my web site so you can get them faster being shipped in the US. I have added a ruler so you can see the sizes. Some kits come with directions and some do not. I will specify if they come with directions. 

Happy shopping and I know you will love his beautiful laser cut kits!

This kit does come with directions!

The base is 2 7/32" wide by 1 5/32" deep. It's so cute!!!
