This is a belt made by recycle V/cambelt/groove armed rubber from automatic doors and beltl lock with original old carabin from parachute airplane. It's 1 inch/2,5 cm wide. It can regulated 4 inch out behind the carabin on the cuttet V belt.
The new carabin is 3 cm long.
If the belt is to long, then it's easy to cut, on the lines, with a sharp knife. And then push the carabin back on the V-belt. Also look at the last picture.
The belt is hard, and best if you add 2 cm to your size.
The groove rubber /V- belt is different from piece to piece, and may vary a bit. It is recycled from cars, and some are more dark black and some black/grey. It depends on what I have in stock.

1 inch = 2,5 cm.

Also have a look at the matching bracelets:
