It’s hard to know exactly what they are without seeing them, because glass tubes can be used for many different things. A few common possibilities include:
1. Laboratory or science tubes
- Small glass tubes are often used in chemistry experiments or for holding small liquid samples.
2. Craft or decorative tubes
- Some are used for tiny vials, perfume samples, or decorative items like message-in-a-bottle style crafts.
3. Storage vials
- They might be used to store powders, oils, spices, or small items like beads.
4. Specialty smoking or fragrance items
- Some glass tubes are used with incense oils, essential oils, or other personal items.
Since they were in a drawer, they might have simply been something your uncle kept for a hobby or project.
✅ Best thing to do:
- Avoid touching the inside if you’re unsure what they contained.
- Wash your hands afterward.
- If possible, take a photo and show it to someone knowledgeable.
