Slim plastic tubes with rubber caps. Simply fill the tube with water, place the rubber cap on top and poke your flower stem into the hole of the cap to create a water source for your flowers. I use these mostly for wreaths and installations, where there isn’t going to be enough hydration. You can reuse these as many times as you wish.
