Launched yesterday, Tetra is the first shop devoted entirely to beautiful smoking accessories like lighters, ashtrays, and incense burners — objects that have either have never before been aggregated in one place, or, more often, have been neglected by design entirely. Marianne Brandt, Enzo Mari, and Dieter Rams created incredibly sleek smoking accoutrements for the home in the '50s and '60s, and Tetra's intent is to revive that tradition in a contemporary way.
