I buy the 3M electrical tape by the pack.
I was gonna ask if he bought "packs" of Super 33+ or Super 88.The super 33+ is still some of the best electrical tape available to consumers.
33+ is theoretically for "Professional" use, not for sale to "consumers". I get it at a Big Box store. About a buck-a-roll cheaper than 88.
33+ sticks better. 88 is thicker.
