COLAVITAPremium Italian Extra Virgin Olive Oil, 25.5 fl. oz., Glass Bottle

Q: I'm a thru-hiker (backpacker) so i count ounces. what material is bottle? glass? plastic? what is the exact weight of one 25 ml bottle?

Going by ship weight for the full set, it breaks down to 1.1oz per bottle, and that's probably an overestimate once you get rid of sale packaging.

Q: approx height/size of bottle in inches? (not weight) Thanks!

The bottle is almost 3 1/2 inches tall. These have been great for travel and camping.

Q: How can you verify its 100% virgin ? just being on lable and from iitaly is not a stamp of authenticity , as a former gov, inspector i need more.

You didn't say what you used to inspect to prove you are legit but I'm surprised as a "gov inspector" you don't know about CERMET certification. What is your question?

Q: This is a plastic jar?

The 68 oz. bottle is plastic; the 25.5 oz. one is glass. Click on the different size options for a photo and description of the corresponding product.
