Aw... so cute! This is similar to the Matchbox Ticket Journals, but cut from lightweight chipboard and sized up to ATC size (2-1/2" x 3-1/2" when folded closed).
Shown in one of the photos inside an ATC Folder (and also in an ATC Tote Box).
This journal is also included in the Spring Flowers Kit; see all the other kit components available to buy separately.
Sold individually (note they come flat, but pre-scored so easy to fold).
