TITAN MANIA titanium chopsticks. Size (approx.): 230mm Weight (approx.): 14g (per pair) Thickness (approx.): 5.8mm Material: Titanium Set includes: Main body This series of chopsticks comes in 19cm and 23cm lengths; these are the 23cm ones. The 23cm size seems to be currently sold out on the official online store. I recently purchased these new. They are very light because they are made of titanium, and they don't have a metallic taste, which is good. However, after actually using them, I realized that I don't like metal chopsticks, so I'm letting them go. I've only used them once at home. I've disposed of the packaging. I am also selling TOWA stainless steel teaspoons and butter knives. If you purchase them together, I will discount the shipping cost, so please let me know before you buy.
