Perfect for ant keeping
These test tubes have the perfect dimensions for ant colony founding. If that’s what you’re here for, then I highly recommend this product. Their diameter is just right for cotton balls to snuggly plug both ends of a would-be claustral chamber without the risk of flooding and their borosilicate composition means they are resilient to temperature extremes/rapid shifts; perfect for sterilizing in boiling water.At first I was hesitant because some other reviews mentioned a complete lack of packaging material. That may have been true in the past, but I can at least confirm that this is no longer the case. I received my tubes in perfect condition with ample padding to boot.I am very satisfied with my purchase.

Autoclavable caps do not seal tube, are more like dust caps
I guess it makes a certain amount of sense that a, autoclavable cap would allow for equalizing pressure, but they do that by not sealing at all. Otherwise the glass part is fine and I figure 3 stars is a C grade, passing but not exceptional

Fine tubes but poor optical quality
The tubes were carefully packed so all arrived intact. I assume that these test tubes will work very well for most application. They are not suitable for my purposes because the optical quality of the glass is poor compared to test tubes I've bought in the past. To be specific, if you try to take a picture of e.g. an insect in these tubes, the amount of distortion is unacceptable. For any other purpose they should be great though.

False advertising the size, pointless caps. Do not buy
Do not buy. The caps are useless as they do not contain liquids. Also these are larger than advertised. They are supposed to be 10ml but they are actually 15ml. So beware if you're looking for test tube that would fill up to exactly 10ml like I was. Also the glass is very thin.

I should have read the the details.
I don't know why I thought they were open-ended on both ends. They are for an autoclave or can be used for beads or pins and stuff. I had different intentions. Prompt and a hassle-free refund from the seller.
