Cardboard Tube STEM & Creative Play Variety Pack – 12 Piece

Build, Create & Imagine with Real Heavy-Duty Cardboard Tubes

This 12-piece cardboard tube variety pack gives kids, classrooms, makers and families a mix of sturdy tube diameters and lengths for open-ended creative play and hands-on projects.

Use them to build toy-car tunnels and ramps, astronaut habitats, towers, bridges, garages, castles, marble-style runs, STEM structures, craft projects and whatever else they can imagine.

Why This Pack Works

• Three useful diameters: 2", 3" and 4" inner diameters create different tunnels, towers and building possibilities.
• Two easy-to-use lengths: 6" pieces are great for stacking and structures, while 12" pieces work well for ramps, tunnels and longer builds.
• Sturdy kraft construction: stronger and more durable than lightweight paper craft rolls.
• Open-ended play: paint them, wrap them, stack them, connect them, cut them or combine them with cardboard boxes and other craft supplies.

Great for: crafts, STEM activities, classrooms, homeschool projects, activity rooms, toy-car play, figures, building challenges and creative projects.

Product is made from industrial-style kraft cardboard cores. Fit with specific toy cars or figures will vary by toy size. Adult supervision is recommended when cutting or modifying tubes.
