Apparently this is not common knowledge. I'm part of a Yahoo group where this was recently shared and I was surprised by how many people didn't know this little tidbit of information. So I thought this would be a good forum in which to share something with you that SHOULD be common knowledge, but apparently ISN'T.
Have you ever had a tough time with the aluminum foil or plastic wrap because the whole roll keeps falling out of the box when you're trying to take some out?
Check out the end of the box. Press in on the little triangle that says "Press here to lock end." That little thing will lock the roll into the box and save you lots of hassle and frustration.
You're welcome. :)
