All vases with a frosted texture may become darker over time or through exposure to touch, eventually reverting to their original color. If you prefer to maintain the frosted look, please follow this procedure:
Wipe the glass with a soft, wet cloth (without abrasive cleaners).
Thoroughly dry the vase with a clean, soft, and dry cloth.
Allow it to air dry for 5 to 10 minutes, and the frosted texture will reappear.
