Masking tape is a tape that can be applied and removed many times due to its low adhesive strength.

It's printed with stylish floral and pastel patterns, and can be used to decorate diaries, notebook covers, and other small items.
As a standard decoration item in the Japanese stationery world, it has become a must-have item for girls who love stylish stationery.
They're available at 100-yen stores such as Daiso, and you can't help but pick them up for their cute looks and practicality.
