Have you seen this design of a stopperless salt shaker? The tiny hole you see on the bottom is where you fill it up with table salt. When it sits on the table, the salt is stored in the hollow interior "donut" in the pot. Give it a shake and the salt comes out of the hole! Very clever design.
And I have new espresso cups in all 4 colours with a black interior. Both the salt shaker and the cup pair up nicely with a little bread & butter plate.
