I use to review items for some sellers a few years back and here is one I liked and here was my review on the item.
You get 12 of these flame-less waterproof floating tealight candles. The are pretty and are waterproof. You can unscrew the bottom from to to replace the batter if needed. They float well in the water without sinking. The lights come on with wet. The is 2 silver dots on the bottom of the lights when you touch them they do light but if wet it is brighter. They would be awesome for a wedding setting or a pool party or for any kind of decorations. They looks great and work well.
