Probably too late for me cuz who knows, you probs bought a real one :3 But u know, whatever the time I hope i can help someone with something they can make pretty quickly using really simple materials!!! And because this is what people will probably be looking into for help, might as well post it here!
DD SO ANYWAY! I actually cosplay Tsugaru and Was actually wondering how to make the pipe myself ^w^ what i did was got a straw (Any straw really, thin, thick, just not the bendy ones) and some model magic and formed the shape of the actual pipe :3! then let it dry for a few days and then cover the base of the straw u didnt cover with paper mache (Because painting a straw is hard X.X XD PERSONAL EXPERIENCEEE) :3 Then just paint however u want!
!!! Heres a picture of what mine looks like :3
(REMEMBER, THIS WAS JUST SOMETHING I NEEDED AND WANTED TO DO A Few DAYS BEFORE THE CON!!! IF YOU DONT LIKE IT, DONT EVEN GO AND START BUGGING ME ABOUT IT! IM NOT GONNA PUT IT IN MY MOUTH ANWAY :P!!!! THIS IS JUST A QUICK OFF THE BAT WAY I DID IT!!! DONT TAKE ME TOO SERIOUSLY, IM A NOOB XDDDD!!! I TRY!!!)
