Thank you for viewing. I am selling this item on other platforms as well, so it's first-come, first-served due to decluttering. The size is approximately 31mm in diameter. Please check the images as this is an old item. I will sell to those who can contact me promptly after receiving the item. I am a non-smoker and have no pets. I will wrap it in air-cushion packaging for protection. If you prefer anonymous shipping, please comment beforehand. Please refrain from price negotiations. I am sorry, but I will not trade with those with less than 5 ratings. If you still wish to purchase, please check my profile first and leave a comment. I don't need "likes"! Please ask if you have any other questions. #patagonia Patagonia pin badge
