I like the colors I purchased, but I was disappointed on the lids. They keep on falling off. I can stack the colors one on top of each other, but then I have to "pry" the lids off. If I lay them on their side, the lids "fall" off.
I ordered five of these on a sale last week. The ink is great, but I will not order any more because I cannot stack them because the lids either won't stay on or stick to the bottom above it--what a shame!
