They were cool.
First of all lots of different hobbies.
Trains, R/C cars and boats, really random model kits (like silly 50s scifi spaceships), dollhouses, cross-stitching, beads, general crafts, you name it.
And they they had a ton of old stock around. I picked up some #modeltrain layout building kits from companies I don't think have existed in decades. And lots of neat little cast metal detail parts from makers I remembered from building models as a kid and hadn't seen since.
