“Sold for parts / repair / resale / restore” → The sunglasses are not guaranteed to be fully functional or wearable. They may be broken, missing pieces, or heavily worn.

“Condition 1–6” → This usually means the seller is grouping items across a range of conditions, where:

• 1 = very poor (damaged, maybe only usable for parts)
• 6 = better but still used (could still have flaws)
  (Exact scale depends on the seller, but it’s not “like new.”)

“No returns” → Once you buy them, you can’t send them back, even if they’re worse than expected.
