Vintage Japan Studio Pottery Drip Glaze selling Cups Saucers Handmade Textured Earthenware Ceramic

Vintage 80's handmade studio pottery pair of cups and selling saucers from Japan (I believe Kagoshima on the island of Kyushu.) These cups have a very unique design with a snake-skin like pattern in dark brown, black, blue and dark yellow. The cups are on the smaller side, measuring 2 1/4" tall x 2 1/2" diameter. The saucer measures a tad over 4 1/2" diameter and has a little lip where the spoon would rest...great detail. No signature on the bottom. In excellent condition with no chips or cracks...never been used.
