Phosphor bronze 10mm diameter 18cm on a side This is a handmade triangle. Made of phosphor bronze. Simply put, it's bronze. It seems to be a material used in high-end models of commercially available products. Although it's difficult to tell from the video, it gives a greater impression of volume than brass. I think it's a triangle characterized by a rich and soft resonance. How about it as one of your sound options?

I feel like it has a certain texture and a dignified appearance. As a bonus, I will include a 5mm diameter brass rod as a beater. I am also selling on other flea market sites. You can also watch the video there. Please note that the price is different due to the commission fees.
