I plan on adding resin kits next, but right now I'm having a devil if a time tracking down ISO containers grin European manufacturers. For example, Minitrix produces both an ISO corrugated 20 box and a slab side box. Is the slash side domestic doing only? Who knows, Minitrix painted it in broad international schemes so I'm trying to find some examples.
Same goes for Roco 20 containers. And those are impossible to find here in international shipping schemes.
After I get the ISO 20, 40, 45 out of the way, I plan on adding resin, laser cut wood and printed card stock.
