To store these pool noodle candles, carefully remove the card stock flames from the tops. Then, store the pool noodle candles and flames somewhere the pool noodles will be safe. I wouldn't worry about water because pool noodles are made for that, but the card stock isn't. I would worry about storing them in a high traffic area where they could get bumped. Pool noodles are only made from foam, so it's really easy to puncture the foam and lose chunks of the foam if people aren't careful around them. If you used battery operated tea lights, you can store them inside the pool noodle candle craft if you are storing them somewhere that won't get wet or damp. But, if you aren't sure about water, remove the tea lights and store them in a box away from any moisture.
