Thank you for viewing. This is a set of a coffee cup and saucer, made with iron powder during the firing process. It has a marking, so I believe it's a piece by an artist. It has a nice aged look due to the passage of time, but I'm selling it to declutter. I believe the purchase price was around 5,000 yen. Please understand that this is a used item and has been stored at home. I look forward to your purchase. Thank you for your consideration.
