I received this as a souvenir, but I never used it and just displayed it in a cabinet. Since I have no use for it, I'd like to sell it to someone who appreciates it. I believe it's Ryukyu glass from Okinawa. The purple color is beautiful. There are some areas where air bubbles seem to have formed during the glass firing process. Please check the images for the size. Since there is no box, I will carefully pack and ship it.
