A little bit fragile

Do not go there like a nag. It is quite fragile as a product made of plastic because, you guessed it. Apart from that, it's nice to keep vinaigrette few days in the fridge in the same container for mixing and serving. (That's why I bought my mother.)

After a little more difficult when there are lumps in your dressing. They will tend to fall to the bottom.

Voila
