OK, time for some wild speculation. Here's what we know:
- For most of the boxes, you won't see the wood. So it will be covered with something. Felt perhaps? Paper? Fabric?
- This is a recurring commission. You only need so much storage, so the boxes are part of the product being sold
- Different size boxes, different size products.
- The product can't be too heavy, since it's 1/2" ply with 1/4" bottoms
- The customer had the good sense to ask Tom to build these things, so he's probably some sort of craftsman, or the creative type.
I say they are gift boxes, that will be covered with fabric to make them look pretty, then filled with delicacies.
