Product descriptions that sell honestly

Write a product description for an online store.

Product: {{product}}
Key specs and facts (materials, size, features, what is included): {{specs}}
Ideal buyer and how they will use it: {{buyer}}
Main concern buyers have before purchasing: {{concern}}
Primary search phrase to work in naturally: {{keyword}}
Brand voice: {{voice}}
Length: {{length}}

Deliver
1. A product title (under 70 characters) that is clear first and clever second.
2. A one-sentence summary of who it is for and what it does for them.
3. A short description in the requested length: lead with the benefit to the buyer, then support it with concrete details from the specs. Address the main concern directly and honestly.
4. {{bullet_count}} scannable bullets in the form "Detail: why it matters".
5. A meta description under 155 characters.
6. One line of care or usage guidance if the specs allow it.

Rules
- Use only the facts I supplied. If a useful detail is missing (for example dimensions or warranty), list it under "Missing info to add" instead of guessing.
- No superlatives you cannot prove ("best", "perfect", "premium quality") and no filler like "must-have". Prefer sensory or practical specifics.
- Use the primary search phrase once or twice where it reads naturally.
