This is a glass plate by Akiko Hayashi / qualia-glass works (クオリアグラスワークス). Size: Approximately 25cm x 2cm Each piece is made using the mouth-blown glass technique, making them thin, very light, and incredibly delicate and beautiful plates. After purchase, I kept it carefully stored without ever using it, but I'm selling it to someone who will cherish it, as I'm decluttering. Akiko Hayashi qualia glass works qualia glass works
