Demon Slayer swords are very popular this year, and if you're going to pick one up, you might as well go with the famous Hashira Iguro Obanai Nichirin Blade.
The Nichirin blade is a cool wavy snake design that compliments Obanai's personality perfectly, and it's made of bamboo which makes it strong but light. There's a plastic scabbard and a candy stripe cotton rope wrapped handle for safe storage of your blade.
Overall length is 38.5 inches. It's unsharpened so no need to worry about safety!
