Place the envelope in your freezer.
Wait a few hours, then take the envelope out of the freezer.
Slide a nail filer under between the seal and the envelope. Slide it a small way to see it the seal pops open. If it does, slide the nail filer the rest of the way through the seal.
Fill a pot with water.
Place the pot of water onto the stove.
Turn the heat to a high setting, and wait for the water to start boiling. Steam should start to rise.
Hold the envelope seal over the steam, so it can reach the seal. Do this for a couple of minutes.
Slide a nail file under the seal to see if it comes undone easily. If it doesn't, continue to steam for a few more minutes.
