It is some friction

Once Anyone who uses the friction ball and I think that there is that it has been experience, but ... when you've spent the rubber without notice that the rubber of friction is dirty gone by and pen stand in the pencil case ·
Although characters disappear, it is not possible to go back anyhow to paper dirty gone. . .
Goodness of precious friction would backfired. There is that.
and (some certain Yeah - I think you ~)

Well, where I bought a dedicated eraser.
This eraser is for us to eliminate this "a complaint" so hard dirt in the pencil case has entered the case.
This will be from noticed I now use the most this eraser when you erase the character was written in friction.
Your heavy user of friction, why not try a once-only eraser.
Please try because 100 yen and (tax) is reasonable.

This Recommended to you!
