how to seal

i was initially disappointed that these ziploc bags didn't seal in any special way. i looked on the sticker mule website. it said, 'can be heat-sealed.' i googled that, and what came up was something that looked like a hair iron, from amazon, for $7.76. since it looked so similar, i googled it again, with 'hair,' and a youtube video came up of using a hair straightening iron to seal baggies. i tried it (i have naturally curly hair, and already have a straightening iron) and it worked on my sticker mule bags.
