These operate as an accessory AND beautifully workable mini harmonica. Let's be real for a moment please.... There are so many opportunities throughout your day that are not musical but could be right?? Please use this while you are looking for your car in the parking lot, or while you are strolling down the street for a nice walk, or while sitting around a campfire, or while waiting for your food at a restaurant (actually maybe not there), but seriously a LOT of opportunity to add more joy to your soul and those around you. Trust me, my family tells me to put it away on occasion, so there is a line, but I can counsel you with that once you buy. ;) Cheapest pleasure right here. Ready, set, BUY.
