The glass test tube is filled with coloured glass gravel that is great to use for art & craft activities. The coloured glass gravel adds a lovely visual and decorative effect in glass vases or jars or when used in small world set ups.
The colour may come off the glass gravel over time so it is best not to use it in an environment with water or liquids.
Warning: Choking hazard, not suitable for under 3 years old. Adult supervision required.
