To use this Nanoblock set, start by laying out all the blocks and the instruction manual. Follow the step-by-step instructions carefully to build your Cinnamoroll model. Be patient as the blocks are very small. Keep the spare blocks in a safe place in case you need to replace any. When you're done building, you can display your cute creation on a shelf or desk. To maintain the model, avoid touching it too often to prevent the blocks from coming loose. If it gets dirty, you can gently blow on it or use a soft brush to clean it.
