Envelope Sealer




Introduction: Envelope Sealer

This is extremely simple, fast, easy to make and works far better than those sold by office supply stores.

Step 1: Items Needed

Find a water bottle and something to poke a pin hole in the cap. Push pin will work best. This is all you will need to make this Instructable. (Oh and some water of course) ;-))

Step 2: Make Tiny Pin Hole

Make a tiny sized pin hole in the center of the cap. Be careful to not make the pin hole too big or you will have soggy envelopes. Start off with a tiny pin hole, test it, and adjust pin hole size as needed.

Step 3: Assemble

Put water in bottle (about half full), and place cap back on bottle. Then turn bottle over and give about one or two gentle squeezes as you glide over sealant on envelope.

Step 4: Finished Results

You should have just the right amount of fluid to now seal the envelope. I personally like the smaller (8 oz) bottles cause they are much easier to work with than the lager ones.

Make one for your secretary or the mail person it will save their tongue.

    another idea would be to affix a tiny sponge on the end so when the water comes out it will just wet the sponge. its closer to the origional.

    Yes it is simpler to use your tongue...but what if you have a stack of envelopes, I sure don't want to use my tongue :-). Also, if the hole in the cap is very small (as pointed out in the Instructable) you won't have the risk of getting too much water. Thanks for the cool comment.
