This “cutter” on eBay is meant to come unfolded and flat (to be stuck to adhesive-film tapes) to serve the users of the tape whenever the following would be an issue without the usage of this “cutter”:
– lack of dispenser,
– weight or size of dispenser,
– safety of usage,
– loading tape into dispenser,
– easy and trouble-free carrying (alone or together with the tape),
– tape end resticking to the roll and/or getting lost,
– glued scissor edge,
– easy/quick tape restart,
– unwanted slitting of the tape.
The “cutter” is meant to be good in all aspects (including changing the tape-packaging process) to be attached to adhesive film tapes.
