we have the collapsibles tub, bowls, tea pot and the salad spinner.
We take the bown part of the spinner on trips and leave the spinner part at home. In addition the uses already mentioned the tub is good for washing dirty dog paws and we use a couple of the bowls for dog food and water the covers keep them from spilling in the car and protect them from blowing debri at the camp site. Bella will nudge me to open them in the car or campsite when she wants a drink or food.
