To complete your own wand, just get some 1.25" PVC pipe (Schedule 40 or Schedule 80) at your local hardware store!
For a smaller, cuter wand like the Cu-Poche Dark Magician Girl, you'll need about 5" of pipe.
For a full size wand, you'll need about 16" of pipe.
To get the gold parts to look shiny, you can check out the
small painting guide on my blog!
I recommend
Rust-oleum Metallic Finish Spray (in Gold)!
