Question on the adjustable measuring spoons... It's really hard for me to sell these! I have them, and I don't really find them that convenient at all. They don't fit into the spice containers, or even into the bottles of the PC spices once you've taken then lids off. I was using them at a show last night, and had to try and quicky shake the spice into the measuring spoon so no one saw that it really doesn't fit. I did play up that they new versions of these spoons do have the rubber slide so they hold liquids better, and people seemed to like that. Any suggestions?
