A roll core is adapted for fitting into an open end of a roll core for supporting said roll core while said roll core is capable of rotating with respect to said handle. The handle includes a hollow holder body having a plurality of side-by-side side wall arcuate segments and a plurality of stiffening ribs formed longitudinally around the holder body, wherein the stiffening ribs are positioned spacedly apart to separate the plurality of arcuate segments into groups of resilient rotor support adapted for compressive constraint within said roll core and derives from such compressive constraint for enabling the roll core to be smoothly rotated with respect to the holder body. The handle further includes a flange radially and outwardly extended from a proximal end of the holder body integrally.
