Although magnetic nail polish isn't that hot anymore I do think the effect is still very nice and the one who invented it must be very clever.
Especially with the Essence nail art magnet pen you can create fun designs; as long as it isn't that complicated and detailed.
For today's nail art I created a simple fall design using magnetic polish and the magnet pen.
