Mostly they're things that are useful and don't take up a lot of space. My jewelry box, for example, is the same size however much I keep in it, and I do wear jewelry. And the little sheets of stickers just get added to general art supply. Some of it I've given to, well, mostly Judith, like a little heart necklace which was more her style than mine, and a tiny roll of starry tape which went into her pencil case. I can imagine passing the rest on. Not sure what to do wit hthe little stone hearts, but they've been the only head scratchy things so far.
The art postcards have given us a smile and been stuck t the wall for a bit but probably ultimately will be recycled, as they're not sent in an envelope but with my address covering the back.

Eventually I'll probably move on and stop, but at the moment, I'm enjoying the surprises and almost all of the stuff has been actually useful, enjoyable things. It's uite customisable, though, so I've got it set to mostly send me craft supplies and jewelry and some kitchen stuff, which suits me.
