The PicassoTiles PTF108 is a 108-piece interlocking disc building set in purple, designed for children aged 3 and up. These plastic chips snap together edge-to-edge to form 2D and 3D structures, offering a screen-free STEM learning experience. The set is made from BPA-free, non-toxic materials, making it a safe choice for toddlers and preschoolers.
What's in the box?
The set contains 108 interlocking disc pieces, all in a consistent purple color. Each disc is about the size of a large coin, with a slotted edge that allows two discs to click together at any angle. No additional connectors or tools are needed.

How the interlocking disc system works
Each disc has a small notch along its edge. To connect two discs, you slide the notch of one disc into the notch of another and press down until they snap together. The connection is secure but can be pulled apart by hand. This simple mechanism allows for flat shapes like flowers or geometric patterns, as well as stacked 3D structures like towers, animals, or vehicles. The discs can also be arranged in a single layer to create mosaics.
Skills developed through play
Building with these discs helps children practice fine motor control and hand-eye coordination as they align and press pieces together. Deciding which disc to place where encourages problem-solving and spatial reasoning. Because the set is open-ended, kids can follow their own ideas or recreate patterns from their imagination. The toy is often used in STEM education to introduce basic engineering concepts like balance, symmetry, and structural stability.
Safety and materials
PicassoTiles states that the PTF108 is made from BPA-free and non-toxic plastic. The pieces are smooth with no sharp edges, and the purple color is consistent throughout the material — not a painted coating. As with any small toy, adult supervision is recommended for children under 3 to prevent choking. The discs are dishwasher-safe for easy cleaning, though hand washing is also fine.
