The plastic was full of bubbles which could be a cool look if I wasn't looking to use them as the beam effect on beam sabres. Worse however is the fact that they didn't have a good way to slot into any of the beam sabre handles of my model kits – even keeping part of connector to the sprue on it didn't work as that was far too thin to stick properly. Looks like the intention is to permanently stick them onto the handle, which is more of a commitment than I want to make since I like to tinker with my models after building them.
