Scented 3M Post-Its are available for this holiday season. The scent is located on the adhesive side of the Post-It and the scent will slowly decrease over time. You have four choices: Cinnamon Apple Pie, Holiday Wreath, Peppermint, Vanilla Gingerbread.
So why give something that's scented? It really comes down to science: Our smell receptors send information to the olfactory bulb, which is part of the brain's limbic system; the limbic system controls memory and emotions, while our other senses (hearing, vision, taste and feeling) send information to the right side of our brain, the cognitive center. What I'm trying to say that the sense of smell is the only sense that causes an immediate [sub-conscious] emotional reaction, so to be able to hit that sense of smell can cause (hopefully) a delightful reaction and fond memory for the recipient (smell = memories). Happy Holidays!
