SQR — Black / Green G15



Choose your frame shape from four distinct silhouettes

Four distinct frame styles, each available in multiple sizes. Mix and match components until every element fits perfectly.

Functional notches at the ear allow personal adjustment without heat or tools. Small, Medium, and Large arms cover every head width.

Three nose pad shapes fit wide, narrow, and low bridges. The contoured design eliminates the gaps other eyewear creates.
Black and classic brown tortoise anchor the collection, while grey tortoise and a subtle green tortoise add interest. Lens and metal decoration finishes are paired to dial contrast up or down depending on your preference.


A biodegradable paper tube replaces single-use plastics. The round shape has superior structural integrity, creating an unexpected and one-of-a-kind unboxing experience. A craft paper insert holds any frame size securely and doubles as a fit instruction sheet.
