Helping my son so much - these work within a couple of hours to flatten ouchie whiteheads. My 14 years old son is so grateful! There’s 2 sizes, 22 patches, and they truly are “invisible” like the box says. These have been working so well (better than any other brand - and we’ve tried them all) and the price is the cheapest. We Love THAYERS brand now - lifetime user here for sure.

Picky dog approved!

Color: S6-muti-color, Color: S6-muti-color

I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣
