Activity kits are pre-packaged sets that include materials and instructions for various hands-on projects or activities. They are designed for individuals or groups, often targeting specific age ranges, and can cover a wide range of interests, such as arts and crafts, science experiments, or educational games. These kits provide a convenient way to engage in creative or educational activities without needing to gather supplies separately. Many activity kits are available for children, promoting skills like problem-solving and fine motor development, while others cater to adults, offering hobbies like painting, gardening, or model building.
