Ember Cairn

Keep matches, a striker and spent ends together

A match safe built as a little cairn of stones. Matches stand in the middle stone under a friction cap, the flat crown of the cap takes a strike strip cut from the matchbox, and the small pebble beside the base is the dish for spent matches, so the kit for the fire or candles lives together.
