Interlocking Gear Construction Blocks, Selected Piece Count

Build colourful structures with plastic interlocking gear blocks in a selected 60-, 100-, 150- or 200-piece pack.

Build and rearrange gear structures

• ✅ Choose a pack for your build – Four piece-count options let you select the amount of material for your project.
• ✅ Try different structures – Interlocking parts can be rearranged into new configurations.
• ✅ Change the visual design – The mixed shapes and colours let you vary the appearance of a build.

Connect and rearrange the parts to create your own constructions. Check the selected pack quantity rather than assuming every pictured structure is included as a finished model.

• Specifications: plastic; selected 60-, 100-, 150- or 200-piece pack.
