Nickel silver Diameter: 10mm Side: 16cm This is a handmade triangle. It's made of nickel silver, also known as German silver. It seems that nickel silver isn't used in commercially available triangles. However, it is used in high-end tambourines. Compared to other materials, it has a hard and sharp sound, but it has a unique impression with more softness than steel.

There are some distortions and scratches on the bent parts, but I don't think they significantly affect the sound. Please be aware of this. I am also selling this on other flea market sites. Please note that the price may differ due to commission fees.
