I like to Reuse jiffy bags when they have been used to send you postal items. Those labels are BIG sometimes....
So to save from tearing them off and
RUINING the item/envelope
USE YOUR HAIRDRYER
AND THE GLUE HOLDING DOWN THE LABEL
Carefully remove and you have a
Jiffy bag to Reuse
Note: always keep in mind what you are heating up
with the hairdryer and be sensible.
