Tape width 0.4 inches (10 mm). The thick tape makes your notebook fun and expressive. [Features] The tape is transparent so you can stick it on top of the text you want to highlight it and make it stand out. If you change the schedule or make a mistake, you can erase it with a special eraser (sold separately). The length can be adjusted. Use one piece to make it easy to use for a long time, and the line decoration is easy. The tape means that you can write from the back, and you dont have to worry about the notebook getting thick or running out of ink. The compact size makes it easy to carry in a pen case. Cannot be written on the top of the tape with a pen. [When using the right hand] (1) Open the cap. (2) Press the head on the paper and slowly pull it hard to transfer the tape.
