Troubleshooting
Pieces are hard to connect:
While designed for secure interlocking, new pieces may require a bit more force initially. Encourage children to use a firm, steady push. Over time, the connections will become smoother. If a piece consistently feels too stiff, try gently wiggling it as you push. Ensure the pieces are aligned correctly before attempting to connect.
Missing pieces:
If you believe pieces are missing from your set upon arrival, please contact customer support with your purchase details. While rare, manufacturing or packaging errors can occur.
Pieces break or shatter:
These blocks are made from durable, bendable plastic. However, excessive force or impact on hard surfaces may cause damage. Supervise young children during play to prevent misuse. If a piece breaks, dispose of it safely to avoid sharp edges.
