Korean Traditional Shadowbox Wall Decor, Korean Poson Tabi (?)

I really don't know much about this item but it is quite pretty, appears to be handmade, and in excellent condition. It is a shadowbox lined with a silk-like (or brocade) fabric which contains a pair of beautifully embroidered traditional shoes or slippers (?) The frame is made of wood and glass. It measures 6.25 inches square and is almost 1.5 inches deep. There is a hanger attached to the back. I saw one like this listed on Ebay Japan and it was described as a "Korean Poson Tabi" It may be vintage, but I cannot say for sure As noted, this item is in perfect (like new) condition with absolutely no signs of wear or damage. Great collectible or gift!
