Masking tape is convenient when you draw a line or frame on a datebook. The slim-series available in widths of 3mm and 6mm is especially useful for arranging a datebook.

Even if you draw a line in an important place as you would use a marker, you can still remove it when no longer needed. This is a very convenient feature.

Different ideas for the slim-series allow for a wide range of possibilities. Why don’t you try using it to make your own original schedule book?
