Belkin has begun shipping several new cases for the fourth-generation iPod nano, the Micra series and Fuse. The Micra cases feature a clear polycarbonate shell with a variety of integrated patterns. Each model adds a different visual effect, but without masking the natural color of the device. The cases include a ClearScreen protective film for the Nano display.

Micra Glam features glass beads molded into the polycarbonate to achieve a sparkly appearance. Micra Dusk provides a slightly smoky tint to darken the case color, while Micra Chex integrates a checkerboard pattern. Micra Flow features a graphic that represents a sound wave.

The Fuse case represents paint dripping on canvas, with two separate sections that link together. The top section is made from high-gloss polycarbonate, while the bottom half provides a matte finish.

The Micra series cases are available individually for $20 or as a two-pack for $25. The Fuse case carries a price of $25 and is available in yellow, red, clear, purple and blue colors.
