Olna bracelet is not a rigid bracelet.
The links have movement as a chain of jewelry, molds to the wrist of your hand. also has a closure to open and close the bracelet. This closure is different from other links on the ball has two planes.
To assemble the bracelet will need grab first the closure and poke one link for it, as seen in the
photos, and repeat with all other links:_________________
OLNA Bracelet 10+1 Link -----> 172.7mm ____________________________________________
OLNA Bracelet 11+1 Link -----> 188.4mm ____________________________________________
OLNA Bracelet 12+1 Link -----> 204.1mm ____________________________________________
OLNA Bracelet 13+1 Link -----> 219.8mm ____________________________________________
OLNA Bracelet 14+1 Link -----> 235.5mm _____________________________________________
My advice: pick a link more than you think you need.
