This is a custom design. I've made a mace, a flanged mace, a flail, and nunchucks. The handle end is pipe insulation, so it is a bit squishy (If it gets floppy, I slide a dowel rod through the middle of the pipe insulation). The business end is stuffed with pillow batting, scrap cloth, or other stuff of that sort.On average, they're about 18" long total, but customizeable within reason.
The one shown in the picture is an example only.
These are made to order and dependent on finding the materials to match your request. It might take 1-2 weeks to make.
The price will vary depending on the complexity of the order. The one in the picture would be $30.
(I'm still working out the logistics for making a sword or other flat stuff, but stay tuned. I'll add a new entry when I get that figured out.)
