The K14 BM is KUBORAUM's K-Series round mask in Mazzucchelli acetate (named in the original product data), finished in Glossy Black with the brand's characteristic hand-finishing visible across the surface. The acetate is thick across the front face, with round lenses cut precisely into the bevel.

Fifty-millimetre lens width, twenty-one-millimetre bridge, one-hundred-forty-five-millimetre temples. Grey lenses, UV protection, unisex single size. The K-Series is KUBORAUM's most resolved round - smaller than the L-Series oversized shapes, larger in acetate volume than the wire-detailed sister L2.
