Review on 12 Magnetic Spice Jars: Convenient Shake or Pour Containers with Easy-Access Window Tops, Attachable to Refrigerator Doors by Heather Johnson

As spice jars they work well, as "magnetic" spice jars they don't really work unless they're half empty or you don't have a lid on your fridge (See video for a comparison of three different refrigerator finishes). Cons: Magnet isn't strong enough when jar is full (only stays on fridge when half empty). Jar not airtight - 1/12 jar slightly rusty Advantages - Shape: square, very compact - Spices are easy to pour or sprinkle, big point because I don't want to unscrew the lid - Can hold the contents of a standard spice jar (just can't be in the stay in the fridge). The main reason I bought them is their "magnetic" functionality. I expected to be able to fill the entire container to get rid of the original jars of my spices and then tape them to my fridge. I think I'll keep them in my drawer, right side up (since they leak a bit).
