Kids love writing tiny notes! We created this “Hello On-the-Go” correspondence kit to contain everything you need to pretend to send mini postcards. Color or draw on one side of the mini postcards, and practice writing on the other - half the postcards are pre-drawn, and half are design-your-own! Please note: not intended to use at the actual post office. Includes: Travel tin (4 1/4" x 3 1/8" x 1"), mini markers, 20 mini color-in and create-your-own postcards. Ages 5 . Small Parts.
