Our T-Shirts Are So Soft & Comfortable
You've found the explanation place!
The things in line behind this thing are our T-Shirts. There used to be a time when I'd planned to have a section of our website for all of our Record Packaging, followed by a section for all of our shirts called "Human Packaging," and I thought that was so funny, but apparently not funny enough that it ever actually saw the light of day.
Our shirts are almost exclusively printed by the saints over at VGKids in Ypsilanti, Michigan, and we do everything we can to find the softest and most comfortable shirts we can. We try to stock a wide selection of sizes, and they're usually all uni-sex cuts.
This "T-Shirts" item is mainly intended to serve an organizational purpose, but has to have a price on it (because this thing isn't built to have items without a price on them, and marking it "sold out" seemed confusing), so we've decided to set a couple options in here to establish the range of prices for these new things we've made.
Note: You're correct that this weird thing is purchasable. That's not really our intention (or is it?), and it's definitely a byproduct of the way the backend of this store functions, but, because we love fun, and we love doing weirdo stuff, I'll tell you now that if you order one of these "things," either out of sincere curiosity or as a goof, we will send you something. Totally up to us, could be cool, could be dumb (but we'll do our best to make it cool, as we always do). You get what you get, no refunds or tag-backs, no more promise, no more sorrow.
