That kind of post is missing key details, so there’s no single definite answer—but there are a few realistic possibilities for small sealed glass tubes (about 5 cm) with liquid found during renovations.
🧪 Most likely explanations
1. Ampoules (medical or cosmetic vials)
- Small sealed glass containers used for:
- injectable medicines (vitamins, anesthetics, etc.)
- skincare serums or treatments (in cosmetic packaging)
- Often found in old homes if someone stored medical or beauty products long ago
2. Old sample vials (chemistry / lab / perfume samples)
- Used for:
- lab chemicals
- fragrance samples
- essential oil testers
- Common in older storage spaces or reused containers
3. DIY or craft fragrance oils
- Some older vanity setups included:
- perfume oils in sealed glass tubes
- decorative fragrance samples
⚠️ Important safety note
Even if they look harmless:
- Do not open or taste the liquid
- Some old medical or chemical solutions can degrade over time
- If unknown, treat as potentially hazardous waste
🧠 Why they might be under a vanity
That location suggests:
- old cosmetic storage
- forgotten personal care items
- renovation uncovered hidden storage from previous owners
🟢 Bottom line
The most likely explanation is old ampoules or cosmetic/sample vials, not anything dangerous—but you should still handle them carefully and avoid opening them until properly identified.
If you want, you can describe markings on the glass or share a photo, and I can narrow it down much more accurately.
