Review on Clear Plastic Condiment Squeeze Bottles 8 Pack 16oz - BPA Free, Ketchup Mustard Mayonnaise Sauce with Flip Caps by Steven Hudson

I needed these bottles to fit the leftovers of the larger bottles and allow me to use partial products. I have things like engine oil, engine conditioner (SeaFoam), gear lube and similar products that are easier to use when put in a plastic bottle. The first thing I put in was SeaFoarm, a very thin oil. So liquid that it could spill where you unscrew the cap. Motor oil and gear oil have a higher viscosity, thicker consistency and do not leak. I suspect that without a rubber grommet or other sealed method. Keep the bottle upright to prevent spills, but I suspect liquid liquid can also evaporate faster than in a truly sealed bottle.
