This may sound odd and is slightly off-topic.
I got a bargain on a handheld box tape dispenser which is similar to this
I'm not at all sure I have threaded the tape correctly because the loose end seems to flap about for a inch or two and is never in the right place to be used a second time.
Maybe my bagain dispenser is badly designed or maybe I have threaded it wrongly.
Can someone here, who I figure might use these things, tell me how to load this sort of dispenser correctly.
