I have a Palm Tungsten E2 PDA and I use the "Poche Toillete 15" to hold it. You can look it up on vuitton.com. Measurements are 5.9" x 3.9" x 1.8". I also use the Poche Toillete 15 to hold extra cards & coupons and it works great!!! My Palm is 4.5" x 3" x .25" and fits in the Poche with no problems.
