The Rakuwa X50 Slim is a silicone / textile necklace of the modern kind. With 50 times the density of the Aquatitan impregnation, it is one of the stronger necklaces from Phiten.
The necklace is much finer than the usual X30 or X50 necklaces. This “slim” look gives the chain a special look.
It is recommended to take the X50 necklace off when showering.
If necessary, it can be cleaned by hand with a little mild detergent.
