Using your Pop & Fizz Beanie is super easy! Just put it on your head and adjust it to fit comfortably. It's suitable for adults in S/M and M/L sizes. When it comes to maintenance, you can gently hand - wash it in cold water with mild detergent. After washing, reshape it and lay it flat to dry. Avoid wringing it out to keep the shape and the bobbles intact. Also, store it in a dry place when not in use to prevent it from getting damaged. Enjoy wearing your beanie with your favorite beverages and outfits!
