Enishi Glass Special Paulownia Box Signed by Yosuke Kubozuka himself. A limited edition pair of rock glasses. These were sold in a limited quantity through crowdfunding in 2020. Please note that due to the handmade nature of the product, there may be slight variations and air bubbles in each piece. I am a fan and have kept these unused with great care. I also purchased another one with a different signature style. Please understand that the wooden box is made of natural wood, so there may be variations in the wood grain color and some age-related staining. Please check the photos. These items have been stored in a private home. There are no noticeable flaws, and I believe they are in beautiful condition without any signs of use, but please refrain from purchasing if you are looking for shop quality. Color: White Type: Rock Glass Material: Glass
