Eh eh! Told you so, guys! Master Cheng is amazing, he's a walking encyclopedia!
Thank you my friend.
Those belts are actually rubber bands. I don't know if this madness has already reached Malaysia (or already left), but here in Europe, every kid has one or ten rubber band bracelets. The interesting point is that they come in dozens of colours, even with gold or bronze tones.
I use two for one samurai, one to hold the wakizashi, and the other underneath to keep it straight up.
PM me if you need some…
