Okay, the user sent "non-reflectives". Let me check the translation rules again. The first rule says to translate all content into Thai. The second rule states if the content is already in Thai, leave it as is. The third rule is to provide only the translation without explanations.
So, "non-reflectives" is in English. I need to translate it into Thai. The word "non-reflective" can be translated as "ที่ไม่สะท้อน" but since it's plural, maybe "สิ่งของที่ไม่สะท้อน" or "วัตถุที่ไม่สะท้อน". Wait, "non-reflectives" might be a term used in a specific context, like materials or surfaces that don't reflect light. Let me confirm the correct Thai term.
Alternatively, if it's a proper noun or a specific term, maybe it's better to keep it as is. But the user didn't mention it's a proper noun. So, translating it as "สิ่งของที่ไม่สะท้อน" seems appropriate. However, I should make sure there's no existing Thai term for it. Since I don't have access to external resources, I'll go with the direct translation.
Also, the user wants only the translation, no explanations. So the response should just be the Thai translation. Let me double-check the rules again. Yes, only the translation. Alright, I'll proceed with "สิ่งของที่ไม่สะท้อน" as the translation for "non-reflectives".
