PLUS PLUS Open Play Set 600 Piece Basic Color Mix - Creative STEM Toy

In this review of the PLUS PLUS Open Play Set 600 Piece Basic Color Mix, the bottom line is simple: it is a flexible, travel-friendly STEM toy that fuels open-ended creativity for children and older kids who enjoy hands-on building. The set's one-shape design makes it easy to start right away, and the included Idea Guide helps when inspiration lags. For families, classrooms, or caregivers seeking a tactile activity that builds fine motor skills and imaginative play, this set delivers a large collection of colorful pieces without screens or complicated instructions.

Key Features

• One simple shape: Every piece connects easily to the next so children can build flat mosaics or three-dimensional models with minimal fuss.
• STEM/STEAM learning: The construction play supports fine motor skills, logic, focus, and early engineering thinking while remaining play-focused.
• 600 pieces: A large quantity of basic colors encourages longer projects and group play, expanding what can be built compared with smaller sets.
• Travel friendly: Small, lightweight pieces and a compact set size make it easy to play during car rides, at restaurants, or on a plane tray.
• Safe materials and responsible manufacture: Pieces are BPA-free and phthalate-free and made in Denmark in a zero-plastic-waste factory powered by wind energy.
• Compatibility: All Plus-Plus sets mix and match, so this kit can expand existing collections to boost variety and scale.

Who It's For

The PLUS PLUS 600 piece set is ideal for children roughly ages 5-12 who enjoy hands-on construction, classroom STEM bins, and families who want a quiet, creative activity that also doubles as a fine-motor skill builder. It also appeals to older kids or adults looking for a calming, puzzle-like craft that can be packed for travel.

Those who should look elsewhere are families who prefer larger, chunky blocks for toddlers under 3 or caregivers seeking highly detailed licensed-character kits; the pieces are small and best suited for school-age users and supervised play for younger children.
