Ten One Design has announced two new colors for its open-back iPad case, Particle. The new Ultraviolet (purple) and Snorkel (blue) color options join Dark Grey to complete the line-up.

The lightweight iPad case comes complete with the company’s signature Pogo Sketch capacitive touch screen stylus. An integrated side clip keeps the Pogo Sketch close at hand and securely in place, and the stylus itself is also rocking a new metal clip.

The Particle’s open-air backing keeps the iPad cool during extended use, especially while watching movies or during gaming sessions. The integrated shock-absorbing rubberized feet keep the device wobble-free and off flat surfaces for scratch-free use. Plus, the rubber material provides traction for stability and control. For added convenience, all ports for the iPad are fully accessible.

The Particle, bundled with the silver Pogo Sketch (a $15 value) is available at http://www.TenOneDesign.com for US$34.95.
