Nice Tubes...

Each one arrived well packed and intact. The glass is heavier than many brands. I use these for flower and plant cutting vases and they work well.


Very good product

Sam W.
Work great. Exactly as expected.

All dimensions match, Good packaging. No complaints, Best price I could find. Used them as windowsill plant propagators.

James Kingman
Glass test tube

All this drive individual rapped. In a small cardboard box to suit the number, you have bought. They are marked as fragile. These have no or very little lip at the opening. All arrived intact. I'm using them as mini vases. I can not comment on there use when heated. Size 15mm wide by 100mm long. They feel nice and look nice.

Item NOT as pictured

Tubes do NOT have a rim as shown in the picture !!!
