A device for dispensing and holding materials wound on a spool having a contoured peripheral edge on a spool end or spool end flange comprising a congruent, self-lubricious member capable of bi-directional movement along the contoured peripheral edge with a predetermined amount of frictional resistance. The member incorporating a material dispensing aperture congruently contoured to the cross-sectional profile of the material thru which the material is dispensed with a predetermined amount of frictional resistance. The member moving along the contoured peripheral edge when the spooled material is pulled away from the plane of the spool end or the spool end flange and generally parallel to the spool core axis during the dispensing process. When the pulling force on the material is halted, the dispensing ceases and the material can then be severed near the member. The end of the material being held securely by the combined "holding force" of the material dispensing aperture on the spooled material and the member being held frictionally secure to the contoured peripheral edge thereby preventing the remaining layers of spooled material from loosening into a disorderly state and also holding the spooled material end ready for future access. The member being readily transferred from spool to spool by simply "snapping" it "off" the contoured peripheral edge of one spool end or spool end flange and then "snapping" it "onto" or "into" the contoured peripheral edge of another spool end or spool end flange.
