Due to the nature of the product, bubbles and chunks of glass may appear on the surface of the glass. The surface may also be uneven, but this is a unique feature of hand-wash recycled glass from Vietnam, which adds to the tactile feel and design.
Glass thickness and weight vary, filling a vase with water and holding only the top part may cause the glass to break. When carrying the vase, always handle it from the bottom with both hands.
