2️⃣ Craft or DIY Inserts
These are sometimes sold as:
Mini rattle inserts for crafts
Sound-making inserts for handmade toys (though glass is less common for children’s use)
Jewelry or art components
The tiny ball bearings create a subtle shaking or rattling sound.
3️⃣ Industrial / Laboratory Components
Small sealed glass tubes with metal balls are sometimes used in:
Chemical testing kits
Calibration tools
Specialty adhesives or repair kits
If ordered accidentally (or sent in error), they may have been part of a bulk supply for hobbyists or lab use.
⚠️ Important: If You Didn’t Order This
If you truly didn’t purchase anything like this, consider:
Checking the shipping label carefully
Verifying the sender
Looking up the tracking number
Contacting the carrier
Sometimes online marketplace mix-ups or “brushing” scams (where sellers send random low-value items to generate fake reviews) result in mysterious small packages arriving unexpectedly.
Do not open or break the glass tubes until you’re sure of their origin.
Are They Dangerous?
From the image alone:
They appear to be simple sealed glass ampoules
No visible liquid inside
No labeling or hazardous markings
They don’t resemble medical vials or anything immediately hazardous, but without packaging details, it’s wise to handle them carefully.
