100Pcs Test Tube 20ml Plastic Test Tubes with Lids Clear Sealing Storage Test Tube Vase with Cork Caps for Liquids Flowers Seeds Sweets, DIY Craft Spices, 15x150 mm

Good product, could be better if it was glass

I have been testing a range of test tubes for bath salts in different sizes, all labelled as PET plastic. However, after a week you can see where the essential oils have started to eat away at the plastic on this particular brand. It is likely that the plastic is actually PP rather than PET.

Excellent item, everything as described - very fast shipment. Thank you 🙂
