M1 - Black availible for the following chain sizes:
Classic 4mm | M |
Classic 5mm | M |
Classic 8mm | M |
Note
The M1 finish is obtained by a chemical oxidation process on a copper surface, which is then cleaned and laquered. This oxide layer is not bonded to the underlying copper surface as in a galvanic treatment and, as such, is subject to wear. Friction caused by normal use of the zip, or any kind of impact with hard surfaces, will remove the oxide layer and expose the red surface copper. For this reason, we reccomend the EB finish when looking for a vintage effect.
The same process is used to achieve BI, EM, EV, FW and Meras M1 finishes and are therefore all subject to the same kind of wear.
