About this activity
Indoor Letterbox Scavenger hides sealed envelopes or folded notes in safe home spots (never real letterboxes on the street). Children collect ‘post’, open clues, and find a final prize book or snack. Structured treasure play for school holidays and after-school afternoons without leaving the house.
