Thank you for sending me an angel
I had a happy moment this morning when I remembered that I'd forgotten to open my Secret Santa present from work. And an even happier moment when I dug it out of its hiding place and opened it to find these Envelope Angels. In case it's not obvious, they're labels you stick over the address on a used envelope to make it shiny enough to use again. They come in two models, original angelic and London Underground issue (above). They're really nicely designed - the box acts as a dispenser which you can refill, and Blue Marmalade, the people who make them are so nice they'll even recycle the plastic stickerbacks for you.
It's only a little thing but it's possibly THEE most appropriate gift as I'd been looking for something like this lately and couldn't find it. And I'm a bit obsessive about recycling, but I've never told anyone at work that. They must have known by the state of my desk or something. So thank you Secret Santa.
