I was subscribed to a Japanese beauty box for a while. It's called Nomakenolife, and cost about £23 a month (depending on the exchange rate for $). I loved it, because you'd get some really fun make up and skincare stuff. One of the items I remember, was a handcare pack, complete with little gloves you wear overnight after smothering them with the cream.
The box comes with a leaflet explaining (in English) what the items are.
I ended up cancelling though, because I didn't use most of the stuff, as much as I loved getting it.
I'm now subscribed to Reading in Heels, which I enjoy. Due to illness, I'd gone through a period of a few years not being able to concentrate on a book, but I started slowly getting back to reading, and I can now manage the subscription book, plus another, lighter read after finishing the subscription book and waiting for the new one.
The advantage to me, is that because the book is chosen for me, I read a larger variety of genres now, and if I was left to choose and order a new book, I probably wouldn't bother, I'd just buy more art supplies with the money! Before that, I mainly read fantasy.
Another reason I love Reading in Heels, is that you also get other items with the book. Usually something to eat, something to drink (tea or coffee), a beauty product, and some stationery or tea light candles.
I really look forward to getting my box.
I'm also signed up to a US stencil subscription (Stencilgirl Club), which is expensive ($35 for international orders) but I receive 3 exclusive stencils each month, plus 20% discount on other orders.
I've also bought a couple of one off boxes from another Japanese site called Neko Box, which is sadly in the process of closing down, but you could choose between a Zakka box, which had stationery, washi tape, paper, etc, or a homewares box. I ordered a cat homewares box, and got a plate, a small saki cup, chopsticks, paper coasters, and a print to frame. And I've just ordered one of their closing sale lucky dip boxes, which should be here next week.
Sad that they're closing, as they had lots of gorgeous Japanese bits, and you could also buy items individually if you didn't want a subscription.
I've been considering Scrawlr, but their boxes seem to be mostly pens. I'd prefer an art box that has a range of supplies, including inks, paints, mediums, etc, but can't find a UK based one.
I'm subscribed to a blog called (I think) Which beauty box (don't think it's linked to the Which consumer guides), and the woman who writes it previews different boxes, and reviews others, so you can see whether it's worth signing up to any of them. She also gets FabFitFun, and her items have looked really good. The original box was seasonal, but they're now doing monthly boxes as well.
