Thanks for posting. 3-in-1 is a popular brand, still exists and not surprisingly even older bottles like this one are fairly common.
Your aqua bottle appears to have a "tooled top" meaning the lip was hand finished after being blown in its mold. Later machine-made bottles would have a mold seam visible to the very top of the lip. (And they would likely be clear rather than aqua)
Below are two advertisements for this product from 1899 and 1921. My feeling is your bottle is likely from the 1890s but could have been made in the aughts (1900-1910) In the teens one starts seeing machine-made bottles. I found yet another 3-in-1 company ad from 1920 which mentions that they can ship a free sample bottle. Collectors know this little green bottle to be machine-made and my hunch is the regular product bottle was as well.
