A couple updates, which are related:
I'm not thrilled with the custom tuckboxes - quite a few of them seem to have had some of the printing rubbed off, and a few are folded badly. I'm going to follow up with the printer to see if they can make it right.
There are enough in acceptable condition to ship out existing orders, but additional orders may be delayed (or, if you are in a hurry to have one, you will be ordering with the knowledge that the tuckboxes aren't in great shape).
Currently, the printer only supports custom tuckboxes for large orders (5000+ cards total), but they are working on supporting them for small orders as well; when that happens, they will be a part of the print-on-demand option which will eventually exist, but in the meantime I may offer the cards without the tuckbox.
The cards I have looked at seem ok, but I would recommend using card sleeves to protect them from damage. If anyone notices issues with their deck, let me know and I can work out getting replacements to you.
