MoMA collections are gathered from all over the world.
Lemnos clocks are sold as standard items at two MoMA shops, one in front of The Museum of Modern Art (MoMA) and the other on a shopping street in the SoHo area of NY.

The cuckoo-collection “bookend / tilt / dent” designed by nendo has been sold since this April and is available from the mail-order catalog and online store.
