Magic ruler / Magic ruler

Magic ruler
Magic ruler

we roll up a painting or something else using sticky tape to keep it .Everthing seems just fine until you open the paper next time.The painting becomes a mess because of the color being dirty.

The magic ruler is made of memory metal materials and coupled with a little magnet . let me introduce you how to use it
1.We need two ruler to put the paper in the middle and roll it up.
In this way,we decrease the friction surface to avoid destory a painting.
2.When you open the paper.draw out the ruler and pressure on both side of the paper to make the paper not curl like before.
