Although it's new and unused, I've washed it again with detergent. Lid: Polypropylene Size: Approximately 18cm in diameter x 18cm in height (excluding the handle) Weight: Approximately 1220g I received this around June of this year and have been storing it. I plan to ship it via standard mail or Yu-Pack, using my own stamps. I will only ship on weekdays. Thank you for your understanding.
