DOGS LOVE
Size: 1 Count (Pack of 1), Style: Heart
My dogs love it! I buy as gifts too as it’s always appreciated. Easy squeak and fun to bounce with all the sides. My dogs chew until they crack & still squeak for a bit. When eventually squeak stops my dogs still return to it. They seem to love just for the air sounds. I personally appreciates that more than the squeak but what do I know? I’m not a dog.6

Great, but they don't last.
Size: 1 Count (Pack of 1), Style: Heart
Our dog absolutely loves these things. However, they get punctured or form a crack on a seam with very little use. This time it only took a couple of hours of play. Once this happens, they no longer squeak. This may sound weird, but the heart shape seems worse for this defect.

My dog loves it - yours will, too
My little merle bulldog absolutely LOVES this toy! It is so cute to watch him play, chew, and toss it all around. We were worried he would chew through the material but so far that is not the case. This product is sturdy and can take a beating!

Great glitter body spray
Color: Fairy-Diamond, Color: Fairy-Diamond
So cute. Came with extra glitter, I’m assuming lipgloss you can make into glitter lipgloss, a funnel to help pour the glitter. Or re load your spray. The spray performance is nice. Might stick better with some oil before hand? But I like it so far. Worked 6 hours and still had glitter on me for my photoshoot. I sprayed perfume and then glitter. There’s no odor. The amount of quantity of glitter you get seems good for the price. Durability seems good so far but like I said may need some oil or lotion first to help it stick all day.

Troll glitter
Color: Brandy-Rose
Do not spray too much! This glitter is so fine that it dispenses easily from the puff part and you can easily make yourself look like Poppy the troll. We had so much fun with this for prom
