Review on Gneiss Spice Small Empty Magnetic Spice Jars - DIY Hanging Spice Rack on Fridge - Hexagon Glass Jars, Magnetic Lids + Spice Labels (24 Small Jars, Silver Lids) by Stephanie Smith

As you can see in the photo I've attached to my review I wouldn't recommend it. I bought the smallest size set that Gneiss offers and after just a few months the inner magnet is rusty and smells awful. The quality is terrible too - they're basically tiny jam jar containers with a metal disc "glued" to the inside with extremely powerful magnets, so when you close the jar they stick to your fridge from the inside of the lid . It would be much better if they used a regular lid on the inside and magnets on the outside, or if the magnetic arrangement in the lid was easier to clean. I wouldn't buy them again.
