We received a small canister as a hostess gift— I thought it was a bit odd of a gift, but now, after 4 years, I really appreciate the practicality of the gift! It’s the perfect size for salad dressings (and other condiments) and is leak-proof (as long as you thread the lid on properly). My 4-year-old kindergartener uses it in her lunch (for her veggie dip) and it fits in nicely in her ‘Go Green’ lunch container’s various compartments. It is super easy to open, yet trusted not to spill. I’m actually wanting to buy more in the future as we will be sending our next oldest child to school in the very near future.
