Fish Bowl With Gravel

Fish bowl with blue gravel, used, but has been thoroughly cleaned and has no chips or wear. I am 99% sure it is a half gallon size, the third photo is next to a Mason jar for scale!

Note: half a gallon is too small for most fish, including bettas. I don't recommend using this for a betta fish as it's not big enough for them to be happy or healthy! Any other kind of fish I would imagine it's too small too, but I'm not sure so I would reccomend looking into it! Could possibly be used for very small fish such as minnows or a terrarium for plants?
