How tall is it? I'm thinking maybe a mid-century shampoo bottle if it's the right size. Amazing to think that shampoo bottles used to be glass up until the 60s or so, wouldn't want to have dropped one of those in the shower!
Yeah that could be shampoo, back then they were often smaller than the ones we have now.The bottle is 4.5 inches tall 3.5 inches wide and 2.5 inches thick. Here is as photo of the bottom.
