We know it seems like the whole world has gone completely paperless, but we still enjoy sending a good old letter, note or card in the mail. It just seems to add a personal touch that email can't always achieve. And while we enjoy taking a classic pen to pad every now and then, we don't exactly enjoy the old-fashion way of sealing the envelope. Luckily, Instructables found a fun way to seal an envelope without leaving a bad taste in your mouth.
Simply apply a thin coat of clear nail polish to the flap of the packaging. This will keep it as secure as wetting it with your tongue would -- if not more. In fact, Wise Bread noted that if the envelope is already fastened and you need to open it, you can use the polish to re-close it. Normally, if you've licked the back, it's almost impossible to re-seal once opened.
This trick is wonderful if you don't have a glue stick handy. And proves that nail polish isn't just to help you get beautified, but it's also really useful to have around the house.
