I recently discovered these pre forms that are used for making water bottles. Frag plugs placed upside down inside these little guys keep the corals from touching noting but water. Once the cap is screwed on, it holds the plug in place. In return, they SHOULD ship better and open up faster because they don't get banged around in baggies during shipping. small frags like zoas, palys, and straight acro frags should do great. Now, we just have to test them out. What do you think? :xd:
