***Please read whole review for full story. Product is good. Delivery was issue.
Color: Light Rose Gold Body Glow, Color: Light Rose Gold Body Glow
I had ordered a bunch of items at once; but within the large box they came in that had no signs of forced entry, there were 2 boxes that were clearly busted open and tampered with, and unfortunately the body shimmer oil was one of them. You can see that someone opened it, and had to go through the plastic to do so, and this makes it concerning for health/safety issues when ultimately using the product. (Speaking in terms of people putting fentanyl on everything). Thankfully I don’t think that’s the case, and the body shimmer oil works as described. I have fair skin and personally I think the shimmer itself isn’t overwhelming or underwhelming- it’s just right. My only issue is that I’m sensitive to perfumes and I find the scent disturbs my respiratory system a bit, making me cough. If that’s not an issue for you, this is a good product.

Best toy for Fetch, Inside and outside. I have multiple of them!
Color: Colors May Vary, Size: 5.5 Inch
Size: LARGE This is hands-down my favorite toy for playing fetch/exercising my dog. I've already bought 2 of these, and I am buying a third because the first one is being rotated out (it got baked by the sun after 3 years outside haha). My Story: My dog LOVES to play. All the time. Inside and outside (well duh, all dogs do). But this toy allows me to play inside while not worrying too much about breaking things. My dog has grown out of his "chew to DESTROY it!" phase, so he is able to keep his toys for a long time. I hate touching toys after they've been slobbered all over, it keeps me from playing with him! There are so many toys that become slippery or slimy after just one throw! But THIS is a great toy because you are able to pick it up with one finger, and just fling it really easily, without getting your hands all gross. In fact, when i'm playing outside with my dog, I actually KICK these (large or jumbo size only) instead of throwing them. They are perfect for that! and I can get a good kick and consistent placement every time with this thing. And then, I don't have to touch it with my hands AT ALL! Reasons I love it: - Non-destructive Indoor Play: I like that this thing keeps its shape, but when it hits things, it just doinks off really lightly and doesn't cause any marks or damage to walls, windows, etc. Note: my house is also not full of knick-knacks or delicate items placed all around that are in harm's way. I'm sure it could knock down some little glass vases if it made contact. The point is, if you place your throws well, you are very unlikely to damage anything in your house (besides your wood floors from your dog's nails sliding all around haha). - Quiet: When you kick/throw this toy, and then it lands on the ground/hardwood, it doesn't sound like a bomb went off in your house. It lands softly and lightly, as if you tossed a half-empty toilet paper roll. I have hardwood at my house, so when I play with other toys, they land on the floor and go BOOM as if you just dropped a 20lb weight! If someone else is playing with my dog with other toys and i'm in the other room, it nearly scares the pants off me. I run in and say, "WHAT THE HELL IS GOING ON --oh, you're just playing! so cute. Sorry, continue on." - Slobber-Free: You don't have to touch the slobbery part in order to throw it or kick it to your dog! Very easily kick-able; it's my preferred method of playing fetch (least energy for me, although I should be the one running, ha). - Easy to catch: Super easy for my dog to catch. He should be a wide receiver cuz he catches things that, when I kick it, while it's in the air i'm thinking, "AW CRAP, that's way too far..... OH WAIT, he got it?!?! noiiice!" Makes an amateur "quarterback" proud lol. - Price: It's not $20 per ball! Some toys are $20 and they make you REALLY have to think ... "Does he REALLY need this toy....??" the answer is always NO, (because he has a million toys that are perfectly good). And then I waver so long on the purchase that I forget it even exists! - Longevity: If your dog is past the "MUST.DESTROY.ALL.THINGS!" stage, then it will last a long time. After 3 years, I'm finally replacing/rotating-out the first one I bought 3 years ago. It has been in the sun, rain, winter, mud; everything. I could still use it; it's totally usable! I was just like, "Eh, why not get a new one?" Honestly, you can never have too many of these. seriously. - Light, Easily Portable: I always pack these in my dog bag. They are light, and they can smoosh into the bag to a smaller size if my bag is full. No problem. - Least-annoying toy that your dog brings to you: My dog likes to HINT that he wants to play by bringing his toys and setting them in my lap (wherever i am). With most of his other toys, my reaction is, "GROSS! it's already so slimy!" and I flick it off of me. This Hole-Y Roller is light and not slimy so you can quickly fling it for your dog without getting side-tracked from whatever “unimportant human activity” you’re doing.
