Repairing or changing prayer bead strings I change the tassel, the "tamlika", and the "tarbozona". And the price differs by type. Changing the "tarbozona" string with installation is 25 riyals. Changing the "karkusha" string with installation is 30 riyals. Changing the "tamlika" string with installation is 40 riyals. 5-day warranty for installation and string. And I use the finest types of strings.
