artxnikki Snail Mail Club

Each month artxnikki mails one never-before-seen 4x6 postcard and a matching vinyl sticker of about 3 inches, both from the artist's hand-painted watercolor style. The designs are kept secret until they arrive, and themes lean toward celebrations, cocktails, friendship and nostalgia, sometimes following the season. The back of the postcard is left blank so you can send it on.

The club is $7 a month with US shipping included; international members pay an extra $2. You are billed on the same date each month, and mail goes out by stamp without tracking, typically arriving within about two weeks in the US and one to four weeks abroad.

The artist recommends it for adults rather than kids.
