Metal, approximately 100g, 18.5cm It has no sharpness and no killing ability whatsoever. I will ship it as soon as possible (weekdays when the post office is open). Basically, it will be shipped by non-standard mail, and if it's large, by Letter Pack. Non-standard mail is delivered by the post office only on weekdays. Due to my busy schedule, I will basically conduct the transaction silently except when necessary, such as notifying the tracking number. Messages are also unnecessary. Please consider that the price includes shipping (excluding cash on delivery) and packing costs.
