I've included details from the official website. Based on the color, I believe it's brass (images 10, 11, 12, 13). There are some minor scratches and dirt, but it doesn't seem heavily used and is relatively clean. Please examine the product page and images carefully before purchasing. I will wrap the wooden box in bubble wrap, cushion it with newspaper, and ship it in a cardboard box via Yu-Yu Mercari or Raku-Raku Mercari. (Items shipped via Yu-Yu Mercari will be changed to Raku-Raku Mercari on weekends and holidays. Thank you for your understanding.) Please take a moment to read my profile before considering a purchase. I am not accepting price negotiations. Thank you for your interest. Thank you for reading to the end. #WaterDropper #WritingUtensils #TakaokaToyamaPrefecture #SSS #sss
