These bottles are perfect! Droppers were covered with styrofoam over bottles wrapped in cardboard corners. This prevents the drippers from breaking during shipping and is the biggest difference to other brands that often arrive broken. Please note that due to the design, drippers are not completely filled. Each pressed dropper bulb is about 1/4 teaspoon, a standard measure for droppers. When I tested, I got the perfect dose of 1/4 teaspoon every time. So don't expect the dripper to be more than 1/3 full. I see this as a criticism in other reviews but that is the standard for droppers. I've found my source for 4 ounce dropper bottles! For your health!
