Puuung Happy Mail Club

Each envelope from Korean illustrator Puuung centers on a brand-new drawing of small, everyday moments of love. Inside are three postcards of that month's illustration, one postcard pulled from her archive going back to 2014, a coloring sheet of the new piece, two removable die-cut stickers and a letter about her month that ends with a spot-the-difference puzzle. One envelope each month also hides a Golden Ticket for a custom portrait.

It costs $11 a month with shipping included worldwide. Sign-ups close on the 20th (Korea time) and each cycle leaves by the 25th; untracked delivery usually takes 2 to 4 weeks. An annual plan adds a thirteenth, members-only envelope.

Ideal for fans of her warm, cozy couple illustrations.
