Lunch box ice packs

A lot of people have been asking me what type of ice pack I use with my kids lunches.  Well here it is.

I got them at www.greenfeet.com.  They are $1.99 per ice pack and I put 2 in each lunchbox.  They are made from non toxic biodegradable gel.  When the kids get home from school the ice packs are still partially frozen so needless to say I am very happy with them.
