I use this tape to cover over my initials on the bottom of my designer vases because my permenant felt markers aren't permenant and I want to insure that my signature stays on my work. I also use this tape over addresses on the packages and letters I sent to protect them from water and not being readable. I also like the width of the tape. It does a great job.
I've tried other generic or store brands which were not worth it. This is as good as the brand name tapes but less expensive. I not have tried the Write-on capability yet.
