It has happened to everyone on one occasion or another: You seal an envelope for a special occasion card or to send in a bill payment and realise you forgot to include an important item in the envelope, or you included an item you want to remove. You can tear open the envelope, but then it is unusable or you have to tape it, which leaves traces of the opening. A better option is to salvage the envelope. Use a technique where you can open a sealed envelope without a trace and then reseal it again. You have two options using common items you have in your home to unseal sealed envelopes.
Things you need
Iron or freezer
Turn on the iron to the low heat setting.
Place your envelope on your ironing board or on a towel on a flat surface. The envelope flap should face up.
Slide the iron over the flap of the envelope. Run the iron over the envelope flap a couple of times. Be careful not to hold the iron on the envelope for too long or you could burn the envelope, and possibly its contents.
Slide the blade of a butter knife under the flap of the envelope. Slide the butter knife along the edge of the envelope flap, where the flap is stuck to the envelope. Gently pry the envelope flap from the envelope.
Slide the missing item into the envelope or remove what you want to take out of the envelope.
Reseal the envelope. Immediately press the flap of the envelope back onto the envelope to reseal it. If it does not reseal, use a glue stick to reseal the envelope.
Place the envelope that you want to unseal inside the freezer. Allow the envelope to sit in the freezer for one or two days.
Remove the envelope from the freezer.
Slide a butter knife under the flap of the envelope immediately upon removing it from the freezer.
Rearrange the contents of the envelope so you can remove the extra item or add the missing item.
Reseal the envelope by running a glue stick along the bottom of the flap, where the gummed area previously was. Press the envelope flap to the envelope to seal it.
