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. 

This kit does not come with directions, but is super easy to assemble with glue. This is the largest of the 3 available the base on this one is 7 1/4 inches wide. 

This kit comes with the LEDs and Battery holder. Batteries are included and the LEDS are already hooked up and ready to turn on!

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