Features:
The TX-2, like most thermal grease, is nothing fancy to look at. Being grey in colour it is also quite viscous to the touch which makes application very easy. The syringe it comes in is covered in a black label with the name and technical specifications printed in white. Down near the tip, the covering has a little window cut out so you can tell when you're getting low.

If you're a novice user, don't worry, the TX-2 is not electrically conductive so you don't need to freak out if some accidentally touches another component.

Installation:
If you install thermal grease properly then installation will vary depending on the CPU type you are running. Since Tuniq does not provide any, I like to refer to the Acrtic Silver site for instructions when applying thermal grease myself. Since I'm running a single-core AMD Athlon 64 chip, it only requires putting a rice sized dab in the middle of the chip's heatspreader, and then a slight twist of the heatsink to spread it out properly. If you are using an AMD or an Intel Processor, or a Dual Core or Quad Core, the application procedure WILL vary. You need to refer to the proper procedure for the style of processor you are using.
