Here's what I have so far:

1" x 2" x 3.5" deep (~1/2 cup)
1.4" x 3" x 3.75" deep (~1 cup)
1.75 x 3.5" x 4.25" deep (~1.75 cups)

Available in aluminum and stainless. Rectangular, seamless, radiused corneres, plain edge, not rolled. Shallow lid, probably need to be held-on and sealed with tape. No handles yet.

These are "standard" sizes but made to order. No idea if the price and lot quantities are sane yet, but if they are I may just order up a few batches.

I'll keep you posted.
