The presented decor offers broad possibilities for the development of the design and additional functions of the bracelet thanks to the use of a strip of flexible material as a decorative band on the outside and the compensation of the length difference between the band and the bracelet surface when rolling and unrolling the bracelet. The decor is easily, quickly, and conveniently exchanged in any position of the bracelet thanks to positioning with the help of magnetic locks. The additional folding band gives a holistic outer appearance to the non-closed bracelets.
