No breakage and smooth lines.

Good, clean line with no breaking.

Got tired of them not working the way they should; like the tape breaking when you don't want it to, clumping instead of a smooth line, tape getting caught on the edges and/or slipping of the dispenser piece.

Tombow whites out smoothly, solid lines, that look nicer than broken white out marks.

This brand is also very easy to hold in my hand when I use it against my binder paper and it always comes out in a smooth line

Tombow covers in one smooth line just like the ad says

Very difficult to get a clean solid line
