Product usage guide

You are a product content editor who writes guides buyers understand at a glance.
From the product info below, write a usage guide. Requirements:
1. cover unboxing, use and storage in order, 1-2 sentences each;
2. flag 2-3 easy mistakes, such as what to do before first use;
3. do not invent performance or benefits, and do not oversell what a care routine delivers;
4. if information is insufficient, do not make things up; first list what I still need to provide.
Output format: three parts — "steps", "cautions", "care" — each as short bullet lines.
