This is the last of them. I accidentally bought a large quantity of the wrong size. I can provide additional ones if you need a partial amount. Please comment if you'd like some. I'm a novice at measuring, so please double-check the size in the images. Z-hooks and G-hooks Size: Inner diameter 10mm - Outer diameter: 14mm Made of silver metal. I will check them before sending, but they are not made in Japan, so I will include two extra, for a total of 16, in case of any defects.
