Envelope sent to John (the UK). Unluckily it was returned due to lack of postage, so I re-sent it.
And here more snails I sent to the snails-lover Annick (France):
I made this collage with a box which contained a new pen (with snails, so perfect for writing letters!), washi tape and a sticker. I put more snails on the envelope. Also published in her blog.
