Phosphor bronze Diameter: 10mm Side: 18cm 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 the impression of having a larger volume than brass. Also, the reverberation is long, and I feel it's a sound that can be used in various scenes depending on how it's handled. If you're interested in the sound, please listen from the URL below. https://youtube.com/shorts/SvO8RBBn-74?si=6ahms88uY16AqxQw In the third photo, I made a slight mistake during production, and it has become distorted. There are also scratches. The material itself is expensive, so the price is a bit high, but I've made it cheaper than commercially available ones to account for these imperfections. It's a material that rusts very easily. Please polish it when you notice it. As a bonus, I'll include a 5mm diameter brass rod as a beater. I'm also selling it on other flea market sites. You can also watch the video there. Please note that the price differs due to commission fees.
