4.5 x 3.5 cm With 3-way metal fittings It gives the impression that it's a bit large as an obi-dome (sash clip). It has a retro and classic feel, but if you pair it with a simple kimono, it might look like Ultraman's 3-minute timer, so it might be recommended for when you're wearing a more vibrant outfit. Because it's translucent, the orange color looks beautiful even when placed on dark fabric ^_^ The metal fittings are not high-quality. How about using it to remake a loose stone?
