I recently spotted few new Sally Hansen Magnetic Nail polishes at Kroger in Dallas. They are shimmer colors with tiny glitter specs.
I spotted these recently in one of grocery store in Dallas, I am not sure what is the price for them, but I picked up some last year from CVS they were around $11, so I think they must be in same range.
As you see they have different prints for your nails when you apply with magnets which comes long with nail polish, they are on top of nail polish covers.
I am not sure if there are any other colors in this collection but they looks fairly new to me. I will post pictorial for one of the old Sally Hansen Magnetic Nail color and which also shows how to use them.
