I received this item and stored it unused in a bag indoors in a dark place. I am selling it to organize my collection. I will wrap it in cushioning material and ship it via Mercari's delivery service in a cardboard box. I have stored it with care, but there may be scratches, stains, or imperfections that are not visible in the photos. Also, I cannot accept returns or refunds for defects overlooked by me, size mismatches, or differences in image. Please understand that this is a cosplay item made by an amateur, and if you are looking for a perfect condition, please refrain from purchasing. ―The following is a quote― This is a replica mask of Ark-One made of FRP. Pearl paint, compound eye light emission Please refrain from purchasing if you are nervous, as it was made by an amateur. ※There is no lining, so please wear a balaclava for survival games when wearing it. We are not responsible for any injuries that may occur while wearing it, so please wear it at your own risk. It is small, so you may not be able to wear it. It locks only with neodymium magnets. No claims and no returns are strictly enforced. ―Additional Information― Although it has compound eye light emission, the built-in button battery is dead, so the usage method is unknown. The battery case has the Velcro for fixing detached. Also, the size feels small, and since I have not worn it, the details are unknown, but I have added a photo with a measuring tape for your reference. ―Additional Information 2― It was a little difficult to measure the inside circumference, so I measured it several times in a front and back split state, and it was approximately 64cm. (For reference, the outer circumference is approximately 70cm.) Please understand that there may be errors due to amateur measurements. The pearl paint and ink filling faithfully reproduce the atmosphere of the main story, and it is a high-quality item. How about it for display purposes? I may delete the listing because I am hesitant to sell it.
