One of the reasons that we made this change was to be able to read the fluid ounce markings on the side of the bottle. With the opague red bottle, these marking were not very easy to read and therefore not very usefull when measuring out the Marvel Mystery Oil. Some customers asked us to put in a clear stripe on the side of the bottle, similar to that on oil bottles, but the type of plastic used would not allow us to do this. Next best thing, change the bottle to clear red bottle.
