Great product! Very small, button lights, with Batteries include. They self-adhere well inside my small pantry and don't get in the way of pulling out pantry drawers. The offer enough light to the darker back section, to see whats back there! Also, put some under the kitchen sink! I had bought a set about 2 years ago. I thought they were pricey, but now, I know they are worth the money. They are easy to install, give the right amount of light, and have an easy to use on/of flip switch. BUT, don't forget to turn them off! I forgot with one of my original set, so it didn't last long. But one lasted for 2 years. They are also easy to remove when the batteries die. I bought the 18pack this time!
