NEW BLOOD

The I-16s (both Soviet and Chinese) are hard to get because they are cheap and you can swarm them. It's a lot of fun to bring 3 or 4 and a decent fighter, but they hit so weak it's hard to actually do damage with them.

I use  generic plastic storage containers that are about 12"X 12"X 3". 

The models are very durable and can touch each other without suffering any damage. If desired a sheet of bubble wrap can be placed between layers.

The models are so durable in fact that (in time) your kid could play with them with your supervision. I let my kids and nephews play with them and now my son is a competitive and willing player
