Fairies, elves, and gnomes love to send and receive tiny notes through our little door (especially in appropriately sized envelopes!) We call it "Lair mail." It's a simple way to get your child excited about using A Little Lair®. We use our tiny envelopes to tuck away money from the Tooth Fairy, little notes of encouragement, or chocolate gold coins just for fun. Download our tiny envelope template here. Finished dimensions: 2 1/4" x 1 5/8".
