Hello, I'm Yannick. During the day I study Electrical Engineering, during the night I design lamps. All the lamps sold on this website are original designs and are printed at my workshop in Amsterdam. To reduce environmental impact, the shells are made of the biodegradable PLA material. The printing of one lamp takes from 2 (Champ) up to 4 days (Rythme). After your order, you will receive a message with the estimated delivery time.
