What's a muggle card? It's a card you leave in a letterbox to explain to anyone who finds your box by accident what they discovered.
The front of these business-card sized cards explains what to do with the letterbox that was found while the back of the card explains more details about what letterboxing is all about.
Muggle cards are sold in packs of 25, at $3.49 per pack (plus $2.50 shipping regardless of the number of packs ordered). View enlarged image
