To keep them in good condition, it's essential to avoid direct sunlight or humidity and refrain from taking them out of their acrylic container for maximum protection.
As they are natural, they are delicate, so it's important to avoid shaking or dropping them on the floor; treating them with care is recommended.
To clean the acrylic container, use a fabric cloth, duster, sponge, soft brush, or a hairdryer. If necessary, you may use water and soap. DO NOT use any chemical products or glass cleaners.
