Building your Itachi Uchiha Nanoblock is easy and fun. Start by sorting the pieces according to their shapes and colors. Then, follow the step - by - step instructions provided in the kit. Make sure to handle the small pieces carefully to avoid losing them. When you're done building, find a nice spot to display your Itachi Uchiha. To keep it in good condition, avoid touching it too often and keep it away from dust and moisture. If it gets dirty, you can use a soft brush to gently clean it.
