Description
Description
The K21 Mask by Kuboraum is available in several colors and finishes. The details in the finish make all the difference in the overall aesthetic.
Kuboraum are masks that are designed on the face of its wearers to highlight their personality and character. Mask is synonymous with mockery and game. Kuboraum masks are synonymous with protection and shelter; they are cubical rooms where we shelter ourselves, free to live our intimacy and look at the world through two lenses. All masks are entirely dreamed in Berlin and handmade in Italy.

Client Experience
“I have always purchased my glasses at discount retailers because I never really saw the point of spending money on glasses, until Gazal Eyecare. The education I got from Andy really made me understand the value of good eyewear.”
— Tanja B.“The care and attention to detail were outstanding from start to finish. Our new frames are truly a piece of art.”
— Karin M.“Sure, it's expensive, but worth it. Also, the glasses last a long time.”
— Don A.“There is a genuine connection that you don't find anymore. When you're there it feels like you are the most important person in the room.”
— Marcus C.“If I could give ten stars, I would. Five for the owners and all of the team plus five more for the product. Gazal is a super well-known and highly sought after designer with her own lines of eyewear.”
— Jim A.
