Kelvira 411 Sand Timer, 15 Minutes

Built for a lakeside cabin used from May to October, Kelvira 411 is the small thing that makes the big thing actually pleasant to use.

Buy a spare before the original wears out — that's the whole logic of a consumable.

It is glass: toughened glass, rated for the humidity and temperature swings of a sauna. Nothing on it is glued into a single block: the walls, the roof and the benches come apart the way they went together, for repair or for moving.

Care

Rinse and air-dry after use; a cabin left damp overnight is how mildew gets started, not the wood's fault.
