We've reviewed many Piel Frama cases in the past, and their quality and style is unfailing. Their leather, or "cow skin" for the Treo 680, 750, 750v and Treo 755p is no exception. It fits like a glove and protects the Treo from scratches, bumps and general altercations with sharp-edged purse and briefcase contents. The case adds little bulk and is slimmer than Piel Frama's older cases, yet it seems to protect just as well. The high quality leather dresses up the Treo, and the case is available in six colors (black, tan, black & tan, red, green and blue).
