The edge of the stainless steel l face is precision cut with two exact lines creating surfaces that both absorb and reflect light. The chamfered face is screwed down with eight stainless steel screws and inset with stainless steel. The interplay of surfaces and materials makes this robust design an ideal gift for the man with an eye on the future, and an appreciation of technical precision. They are presented in a stylish matte gift box. Materials: Stainless Steel Dimensions: 0.83"L x 0.69"W x 0.69"H; 0.5625 lbs.
