Setup
Upon receiving your Melissa & Doug Standard Unit Solid-Wood Building Blocks, follow these steps:
- Unpacking: Carefully remove all 60 wooden blocks and the wooden storage tray from the packaging.
- Initial Inspection: Inspect all blocks for any signs of damage or rough edges. While the blocks are smooth-sanded, a quick check ensures optimal play safety.
