Thank you for viewing. This is an unopened Fitty mask. I purchased it previously and stored it at home. I will give it to someone who can use it. Size is approximately 14.5cm x 9cm (slightly smaller size) Due to shipping costs, the outer bag will be opened and only the masks will be shipped. Although it is unopened and unused, please consider purchasing it with the understanding that it is a used item. I do not hold items. I prioritize the person who purchases first. Thank you for your understanding.
