I always put 2 teaspoons of sugar into my tea. This is a pain, since you have to either tear open two little packets of sugar, or else get a spoon for measuring it out. This device makes the whole ordeal go away, dispensing two teaspoons into your cup withy a flick of the wrist.Threads onto a standard Anchor Hocking-type glass sugar dispenser body, available e.g., at Smart & Final, Wal-Mart, or, on the internet, e.g., here:http://www.retroplanet.com/PROD/10090You're done!To use, fill the glass thing with sugar, and put the cap on. To dispense, turn the whole unit upside down (so the spout fills with sugar), then right-side-up again (so the sugar pours out of the spout into your cup. It's easy, but you may want to practice over the sink!
