Review on RSVP International Endurance Collection: Dishwasher Safe Fine Mesh Stainless Steel Kitchen Shaker Set by Courtney Stone

The mesh is very fine. You can't just use it for flour because the flour will clog the sieve. Choose Endurance's Universal Shaker when you're looking for a flour digger. This works great for powdered sugar and I assume it works for cinnamon powder as well. In fact, I can use it for a cinnamon powdered sugar mix, since anything that tastes good with powdered sugar will probably taste even better with cinnamon. Just note that I don't think the plastic cap is airtight. It's not that tight. If you really want airtightness, you'll probably need to cover the shaker with tape before lowering the top down.
