I purchased this 4 pack oi f underwater lights by #KJOY as they have so many uses. I love putting the mb in the bottom of a clear flower vase, add water and flowers and present them as a nice hist or hostess gift. In the middle of dinner I'll surprise them as I reach for the remote and turn it on a nice red, blue, green or other color. The shock and awe makes it worth it. I also live to add them to bottom of shell crafts to create an underwater effect. I just bought a fill up cylinder lamp that I intend on using one of these lights on the bottom and fill with seashells. Then I can use it to create an underwater effect on th at also. Because they're waterproof you can put them inside a fish tank, put one on the corner of a desk or bedside table to create a "mood". The options are endless. Here you get 4 lights and 2 remotes for $29.99 which is what you'd expect to pay for such good quality. Very reasonable. I highly recommend this set for all you crafters, decorators and even gardeners. Makes a great gift, especially if paired with a vase full of freshly cut flowers in water.
