Storing your "Dr. roller" brand dermaroller

[dannu]

What is the best way to store my Dr. Roller?  It comes with a plastic cylinder but the roller isn't secure in it and the needles would be hitting a surface.  Am i supposed to just reuse the sealed plastic encasement it originally comes in?  Is there another special case I can buy?  Thanks.

The plastic box is made of thermoplastic material, so itä's very soft. It's a  principle of physics that a softer substance is not able to scratch a harder substance, so the only thing that could theoretically happen is that the needles would bend.

This is however totally impossible in practice, since you would have to use tremendous pressure, pushing with extreme force to cause the needles to bend.

The storage container for the Dr. Roller is intended to be able to clean the roller in. It's actually a very clever solution.
