We love the natural, acacia wood tops, and even the plain white porcelain looks warm and creamy. They have silicone sealing to keep the tops tight, and some have transparent windows in the lid, so you can see what's inside.
Of course, as with all things Ikea, it's best to be able to inspect them in person. We didn't see these on our most recent trip, but we're on the lookout now. They're just so pretty and unobtrusive all gathered together.
There are also an oil and vinegar set and a soy sauce pitcher. So far, nothing's available online, but you can get more info here:
