Width: 18mm Please check the remaining amount. Please refrain from price negotiations. For combined purchases, I will adjust the price after listing if you request it without a discount. If the item was listed during a campaign period, I will combine them on the listing page instead of accepting your request. ⚠ If you decide to sell the item on Mercari or other sites when you no longer need it, please retake the photos. Do not use the existing ones. ⚠
