A Multipurpose Tape Black Silvertec Tectape is similar to the popular duct tape, However is black instead of silver. I found it in a shop of the Kalunga from a Shopping Center, by R 7,40.
Check out some photos of Multipurpose Tape Black Silvertec Tectape and your packaging:
The roller has 5 meters tape, with 38 mm width. I used it to fix provisionally the arm of my chair, that's with a tear on the foam. The repair was not nice, but at least was more discreet than if it had been done with duct tape silver:
The repair was done two months ago and is still in one piece, same with the Chair being used daily.
A Multipurpose Tape Black Silvertec Tectape got back in polyethylene film, reinforced with laminated cotton fabric and covered with rubber adhesive.
