I went to the Lego store yesterday and got a PAB cup for my birthday, paid for by my friend. (He has a Lego VIP card, so that does help him get some points for discounts)
About this creation
I fit 10 2x2 orange slopes into the lid, but they weren't as snug as the last configuration that had 8.
I probably could have filled the bottom better, but I didn't see it at the time.
The not-so-exact inventory should be up eventually.
