If you need a compact scale that you can take anywhere with you, check out this Card Style unit by AWS. 

It's small and easy to carry in your bag, and comes in a storage pouch that further protects it from damage. It's designed for measurements up to 600 g and can recognize 0.1 gram increments. You can choose to weight in several metric units and the results will come up on the backlit digital screen. 

The color of the scale may vary, and it's made in gray, blue, silver and black. It's backed with a 10 year end user warranty that testifies to its long-lasting performance.
