I bought a thing at 7-11

Our dog has a game in which she constantly wants you to throw this mini-sized tennis ball for her. It drives me up the fucking wall. I've never been one to pick up the slimy tennis balls dogs foist on you, so today I bought a toy at 7-11 which should ameliorate our situation. It is called EYE SIGHT CHALLENGE and it is Made in China. Can you guess what it is? No, of course you can't. It's a little red slingshot. Ah, who doesn't look fondly back on those innocent days of youth, spending hours with one's young chums, trying to knock down tin cans to see who would win the eye sight challenge.

Even more curiously, the package is decorated with these waving checkered flags.
