Thank you for viewing! (*^^*) Fujiya Peko-chan & Poko-chan Collection Interior Doll Set - Peko & Poko These were received over 20 years ago through a point campaign. They were displayed in a showcase without their original box, but for some reason, there are stains on their faces. I tried wiping them with a wet wipe, but the stains didn't come off. I'm afraid of discoloration, so I haven't tried using detergent. Yellowing of the clothes can also be seen.
