Magic Memory Pen / Mark Pen

Magic Memory Pen

We need to exercise repeatedly during learning. To test whether we have remembered or understood the knowledge, the important part should be hidden. This is trouble for learning. The “Magic Memory Pen” is a type of mark pen that realizes masking word easily. Cover the important content with mark pen, and then this contend would be hidden with help of the green filter glass in the middle. That is, the content disappears when it is looking behind the glass. But if we remove the glass, the content comes up again. This product can help the learner to remember and exercise quickly without damage the book.
