OK, its been a while so here's a new one:

These are resin 3D printed parts to full body kits. It looks like everything is US based and 1/24 to 1/25th scale. Lots of possibilities here, from diorama parts and pieces to engine kits to batteries, turbos, and carbs.
A couple of items I spotted were the 1/25th scale spray paint cans for dioramas and the "Tommy and Cheech" figures (seated or standing).
Lots of items to take your 1/25th scale build to a higher level.
