The Module Blocks set features 21 oversized blocks, each measuring 12 inches, designed to encourage large-scale building and creativity. The blocks promote collaborative play, helping children develop teamwork and problem-solving skills. Constructed from durable vegan leather, they are built to withstand frequent use. A separate Angeles Universal Cart Organizer is available for mobile storage, though it is not included with the blocks. This set is suitable for children ages 18 months and up.
