Beautiful black and brown gradient yunomi teacups, made by Ryumonjiyaki Kiln. Likely a pair of couple's teacups. - Color: Black and brown gradient - Diameter: Approximately 7.5cm - Height: Approximately 6.5cm, approximately 6.7cm The bottom of the item on the left has a crack, likely from firing, but it does not appear to go all the way through (see photo 3). There are also uneven patches of glaze on the inside (see photo 5). The outer box has some stains due to long-term storage.
