I don't know if you are like me or not, but I use ziploc snack bags all the time! Mike and I both usually pack our lunches so they get used there. Whenever we go somewhere and Zoe (our dog) tags along, I put some treats or her food for the day in a plastic ziploc bag. The uses for those things are endless and I tend to use them a whole lot! That sure isn't very GREEN of me! Or economical since once they are used I have to throw them away and eventually the box is empty and I have to go buy more!
These little bags can be used for snacks in lunches, travel bags, etc. The uses are endless!
They are 100% machine washable too which makes for easy clean up!
