These clear food-safe bags have a 4" x 2" base and are 8 1/2" tall but you can always trim smaller for the cupcakes or little goodies! Tie with a ribbon or add a gift tag or label (makes them easy to close!). If you want a more colorful look the #10 backing comes in lots of colors (you just need to fold the backing flap over and embellish with ribbon - the holes are already provided!).
PS: While you are there make sure you check out the hang tags as well - they are having a huge sale right now and these would also make a cute tag to use on these bags!
