Ok I made 2 syringe tanks thanks to David for the video! Since I knew I wanted pretty (ok I am a girl after all!) I went looking for things to dress it up before I made it. I found this transparent window film and low and behold they send out free samples. I mean free even the shipping and handling. Yep thats right I got the maximum 5. lol Each sample will cover about 2 of the 20cc tanks. I went with the brighter but darker colors ...they are pretty but ya kinda have to hold them up to the light to see the fluid level so you might want to go with lighter colors. I now have a pretty blue tank and a pretty purple tank. I think they are also easily removable if you decide you don't want that color anymore. Mine peels right off if I want to but I have to intentionally peel it off cause its on there solid but I have only had it on there a couple of hours so don't know what its like after a few days. Ok here is the link to the company https://www.decorativefilm.com/ . Might be good place to buy from for those that make alot of these mods.
