Yes, children can build some of the easier Ugears mechanical models on their own, or assemble some of the more complex puzzles with an adult’s assistance. For kids ages 8+, Ugears have mini 3D model kits. We definitely can say that a child of 14 years old can assemble our models. Sometimes they will need parents’ or grandparents' assistance. Our mission is to give people of all ages, especially families, the enjoyment of creating something beautiful together.
