I wanted these to transport watery liquids on road trips with changes in elevation, so I filled one most of the way with water and turned it upside down and squeezed (to simulate a change in air pressure). I was able to force water out around the snap-on cap. The screw-on part of the cap held just fine. I reported this to the vendor to find out how they wanted me to handle an open package that didn't meet my needs, and their response was that they were designed for home use and to use them at home.

Good quality and cheap price!Use one for oil dispenser so I can eat less calories. Use another one for wine dispenser to easily put the right amount of wine needed for fish floss.

Great for dressing and salsas.

I use these in the kitchen for different oils and vinegars. Work well and don't leak when upside down.

Love these bottles. Make things more practical

Purchased for Resturant use. Great product.

Bought these to use for storing paints for acrylic pouring. The spout is small enough you don't get too much at once and none of them leak.

Chemical plastic smell. I would not use it for food or sauce. I didn’t return it because i’m going to use them for paint pouring.
