Playwood Connectors are an innovative solution for screw-free and tool-free assembly of modular furniture and storage units. Simply use the connectors to join panels in your desired configuration and tighten with an allen wrench. With Playwood Connectors, YOU are the designer and the sky is the limit! Playwood Connectors come in 90-, 105- and 150-degree angles and a variety of colors to provide you with maximum design flexibility. Because they require no extra tools or hardware, the structures you create are easily disassembled to create something new as your needs change! Manufactured in Italy by Space Matters, Playwood Connectors are made from glass-fiber-reinforced plastic, making them incredibly strong and resistant to humidity and UV rays -- use them indoors or out! Ideal applications: workshop or garage storage and organization, kitchen storage, bedroom furniture and storage, outdoor furniture and storage, preschools and classrooms, dorm rooms, apartments, small offices, and trade shows! For use with panels between 16mm and 19mm (.63" to .75") wide in material of your choice -- plywood, laminate-coated MDF, etc. Includes four (4) white 150-degree connectors and one allen wrench.
