Core features

Star Trek™ x Holzkern

Celebrate the iconic Star Trek series with the stunning pieces crafted as part of the Star Trek x Holzkern collaboration. Boldly explore our distinctive designs, blending natural materials to capture the essence of deep space and the thrill of interstellar exploration. May these pieces not only honour the adventures of the past but also inspire excitement for the countless journeys ahead!

Our Bandlets—the modern alternative to jewelry

Real wood, sturdy stone, and robust Stainless steel come together in a wide, link-style design that gives the piece a noticeably more striking presence. Easily adjustable to fit your size and made for anyone who prefers to swap delicate jewelry for one-of-a-kind pieces with a bit more character.

Hydro-Defense Technology

Our HydroDef technology takes the resilience of natural materials to the next level. By means of a special resin coating, exposed elements of natural materials are significantly better protected from weather conditions (especially water).
Hydro-Def makes your piece of nature a faithful companion for all-purpose wear!
