It is a very useful product as a use, but the adhesive strength is a little weak.
It is the third purchase this time, but there was a glue residue.
It is regrettable because there was no adhesive residue in the past two times.
The manufacturer's blindfold tape has been discontinued and I found this item where I was in trouble. Usability is pretty good, but the adhesive strength is too weak, peeled off at the time of fax reading, many things became transmission without blindfold. On the contrary, it is attached to the inside of the FAX, causing image dirt and paper jam. I would like to have a regular purchase if it increases the adhesive strength, but it is a very regrettable item.
