I have bought several orders through KB3D and every single order has been quick to ship and always accurate. I recently asked for something not listed on the site and they were very accommodating. I'll buy again for sure.

It took a bit longer than we thought but the good people at KB3D LLC kept me informed of the unforseen delays. The loom quality is very good and well packed so that you know what goes where. Thanks to the KB3D team.
