10 Pack - 20x150mm Pyrex Glass Test Tubes with Rubber Stoppers Review

Pro- Stoppers seem to be of adequate quality - In fact I'm using them in my quality test tubes right now!
Pro- some test tubes arrived in the condition expected

Con- Four test tubes were completely shattered in the box.
Con- This is arguably a culture tube, not a test tube. One assumes test tubes have flared lips to allow for an easier time pouring fluids. The lip on this 'test tube' is so thin that I am extremely worried that the tube will shatter whenever a stopper is inserted for an air tight seal.

I am unsure if I will be using this product at all, the glass lip is thin enough to concern me.
