This tape just didn't want to stick. It didn't make a differece if the boxes were new or used the tape would come undone. Think you had boxes sealed then your sitting there listening to strange sounds only to find the tape coming undone. We really had to do a lot of rubbing to get in to stay hafe way.
Yeah it's tape. It works like tape. You stick it to stuff and it stays there kind of magically and kind of like tape. I don't think it would be as useful as duct tape in an emergency situation unless that emergency constituted needing to seal a package for shipment in which case this tape fits the bill perfectly! Good cheap tape that is quite useful for taping stuff. And having 6 x 110yd rolls would give you enough tape to lay the length of 3 football fields 2 times with enough left over to tape a few boxes shut!
The price drew me to buy it first but I came back to it after trying another store's brand. The tape is better quality the roll lasts longer and the price is better.
