Using this puzzle is easy. Just take out the pieces and start assembling them one by one. Look for the edges first to form the frame. Then, start filling in the middle based on the colors and patterns. Since it's a glow - in - the - dark puzzle, you can charge it under bright light during the day and enjoy the glowing effect at night. When handling the pieces, be gentle to avoid breaking them. To keep the puzzle in good condition, store it in a dry place away from direct sunlight. If it gets dirty, you can use a soft, dry cloth to gently wipe the pieces.
