Yes, they are for drinking indeed. I have some at home too

They would be to use as a drinking cup with a straw. Although you could use them to try growing sprouts in

I’ve only ever seen these used for drinking, with straws.

You could buy replacement lids if you wanted to use them for storage.

A drink you put a straw thou the little holes.. Some tendy out there cafes/bars use them for that reason..

It looks like Mason Jars. Kmart.Target sells them except they have a red/white straw in the middle. My daughter got excited and bought a couple as they are not dear and I said what is wrong with a drinking mug ?! . It is really a novelty by the looks of it . It is storage for storing liquid and drinking from it .

I think that you use them for drinks indeed, like smoothies. I know that there are some mason jars that you can screw directly into your blender and then you drink directly from it, and carry it with you when you go out.

I’ve only ever seen them used as drinking jars, the holes in the lids are to put the straws in. You couldn’t store much in them 1) because of their small size and 2) because of the hole in the lid

Its the new trend of drinking from a jar

There drinking jars with the hole in the lid used to put in straw.

Using jars with straws as drink glasses seems to be the new trend. If you wanted to use them for storage, I would place a piece of durable tape over the hole (both on the outside and inside of the lid) to keep air out. I hope this helps.
