These magnets are great. I especially appreciated the packaging, they had plastic spacers between the magnets, which really helps in getting them apart. It was also nice to have the double sided adhesive pads to go with them. I didn't see that in the description, but definitely made my project look much nicer. I used these for spice jars. If you are buying then for that purpose, then get a jar smaller than 4oz. These will hold an empty 4oz jar, but not one filled with garlic powder. However, I still liked the magnets and the size for the jars I bought, so I just changed my project. They won't be going on the side of my refrigerator now.
