FAQ'S

Q: Is the printed manual attached with the kit?
A: Yes, every kit is shipped with printed assembly manual.

Q: How are the sets secured during transport?
A: Each set is packed in a cardboard box. We do not ship in bubble envelopes.

Q: Did you offer assembled boards?
A: For kits which are more popular we plan to introduce assembled version, but actually all kits are available as a kit for self-assembly.
