Review on Essential Teenitor Reducers Transfer Droppers by Angela Banks

I bought these bottles to sell samples of essential oils. I have had several "samples" purchased from me and all my customers have complained that they had to remove the plastic hole (which spilled the oil sample) because the oil would not drip out of the bottle. I assumed my customers weren't patient and took their time to drop the oil. However, after experimenting, I found that I couldn't get the oil to pour from these bottles! I am so disappointed! I've tried different amounts in bottles, holding the bottles at different angles, different types of oil, and the oil still hasn't fallen out. Maybe I caught a faulty batch? I read several other reviews about this event. I am so disappointed. and embarrassed because I had already distributed my samples with those bottles!
