Ah yep. They do now! I'll get back to you about those
Edit: So I think around €4 for the eraser and the pin-thing (it's damaged though, so perhaps a bit lower)
The bracelet, maybe also something like that, but I don't see that one as often (I need it
). I believe it should usually be joined by a second one? I'm not really sure though, since I don't have it mip. But I have a green one like that.
