Durable Protective Two Tone Rubberized Crystal Hard Case Cover with Stand Alone Kickstand for Apple iPod Touch 4th Generation 8GB,16GB and 32GB - Pink
My four year old has been using this on her iPod for 10 months now and it still works great.  I figure if the kickstand can make it through 10 months+ of preschooler use, it is a pretty great product!  I would definitely buy it again.
