Ref. : FBLS.01.BC.06 / FBLS.01.BC.07S / FBLS.01.BC.08SClasps FBLS.01. BC.06, FBLS.01. BC.07S and FBLS.01. BC.08 SI have the same construction of the blade. It must be emphasized that the operation of FBLS.01. BC.08 SI is different since the commitment is on the side and the security is integrated into the box. The slightly oval shape facilitates the opening and closing of the clasp.
