I searched Amazon - if your referring to these: https://www.amazon.com/Rectangle-Apothecary-Bottle-Airtight-Phenolic/dp/B07H8S6VVM

Then save your money. Also, if all ya are using diphenhydramine 12.5 mg/ 5 mL - I would seriously think about increasing your charisma skills and try to win over a pharmacy manager. Why? Because when it comes to bulk OTC products, it’s a hell of a lot cheaper, pretty sure it’s like $12.99 for a 16 ounce bottle (473 mL) of Benadryl

Let me know if your unable to get the 2 ounce bottle with the adapters. If ya can’t, I’ll post a photo of what I’m talking about so ya can get a better idea of what I’m talking about
