Mirrored crystal, cut with rounded corners and a slightly curved edge, forms an illusory frame around the Glenn mirror. The edge distorts the reflection at the perimeter rather than giving a sharp cut-off. Glenn can be hung as a square wall mirror or installed as a vertical floor mirror, turned to its long side when a horizontal format suits the room instead.

The crystal is available in various finishes, with sizing set out on the spec sheet. Cattelan Italia also makes Glenn Magnum, a larger version of the same design.
