To use this Nanoblock set, simply follow the detailed step - by - step building instructions that come with it. Start by sorting the blocks a bit if you want, it can make the building process easier. Be careful when handling the tiny blocks as they can be easy to lose. If you accidentally drop a block, take your time to find it. After you finish building your Pompompurin model, you can display it on a shelf or in a small case. To keep it in good condition, avoid touching it too roughly as the blocks might come apart. If it gets a bit dusty, you can use a soft, dry brush to gently clean it.
