Sturdy, great value, very utilitarian
Size: 50 Count
Exactly what I wanted. Exact quality thickness and sturdiness. Only small downside is they're coated in a wax like substance and stick together so you have to pry them apart and if you microwave something, it tends to meld together and also stick into the bowl. But I still love them especially the price.

Awesome Body Lotion For Dry Skin and Some Reduction Of Age Related Wrinkles
Scent: Sweet Vanilla & Soft Wood, Size: 18.5 Fl Oz (Pack of 1)
I have only been using this product for a short period of time, but I very much like the fragrance. The sweet vanilla and soft wood scent is a great combo and not overpowering. I like the texture of the lotion, which is a silky smooth clear gel and easy to apply. My age wrinkles are diminished and very much less pronounced. It makes my skin feel more supple, as I have dry skin and the lotion is perfect for that condition. It will definitely be my go to skin lotion going forward as I am very pleased with the cost and the improved skin condition is a very short period of time.

Eradicated Decade Long battle with KP on INNER KNEES in less than 1 week. NEW KP HOLY GRAIL CREAM!!
Scent: Sweet Vanilla & Soft Wood, Size: 10 Fl Oz (Pack of 1)
About my skin- 43 year old fair, normal to dry, very sensitive, prone to KP bumps on back of arms, inner knees and if aggravated - all over thighs. I am pretty careful with what I use and I even have to be careful within the same brand if something DOES work. I have spent a long time being snobby about “drugstore” brands because over the years they have all aggravated my now mostly under control KP. I recently was convinced to try the Olay SUper Serum body wash because a friend with similar issues said she was really impressed. I have been also! In fact, the body wash for “Rough and Bumpy” skin has been my go-to wash for the past few months and has visibly improved my overall skin texture and has not aggravated any KP flare ups. I was very excited to try this body cream, since the current one I use is over 50 dollars for a similar size jar. I like to use A LOT of moisturizer and the cost is really annoying and close to being prohibitive when you use a jar a week. I purchased this cream (packaged well, no leaked, fresh product, overnight delivery). I am in LOVE! It smells great, very high end. The fragrance is real so if you hate fragrance, bot for you. I wear Baccarat Rouge and this lotion does not interfere with that, and it does dissipate after a while (I asked others to be sure). The crazy thing is this… most of the time my KP bumps on my inner knees are there, but when I have them under control they just lack color and are a lot smoother. THEY ARE GONE AFTER 1 WEEK.. THIS IS THE FIRST TIME IN THE DECADE OR SO I HAVE HAD KP BUMPS ON MY INNER KNEEES THAT THEY HAVE BEEN COMPLETELY GONE. I do not feel it is the combo of the wash and this cream, as I have been using a different wash while out of town. The only new item I used was THIS CREAM, alone, without my other more expensive product. I am kind of blown away and delighted. Also, I was able to use less of this to feel moisturized than I have been using with the “fancy” brand. The scent is warm, slightly vanilla, expensive and not too floral. Cream absorbs quickly and well, leaves skin feeling plumped, soft, no greasy residue and MAJOR BONUS… NO PILLING. That is a nightmare when a product does that. It absorbs quickly, leaves no marks on clothes when squeezing into a pair of black legggings…. All the good stuff you may forget to look for but notice when they happen. I HIGHLY RECOMMEND TRYING, if a light, high end fragrance is good with you. To reiterate- the fragrance is not crazy strong but it also calms WAY down about 30 mins after applying and melts into just a nice feminine clean but warm (not body spray type of vibe) scent that is not very noticeable to me or others. No where near as strong as like a Bum Bum cream (which I LOVE IN SUMMER) and smells high end, not like cheap shampoo or air freshener. Get this!!!!!!! It also did not irritate my chest area which for me is always a little prone to red spots when I use fragranced products. No irritation and dude… NO BUMPS FOR FIRST TIME IN A DECADE OR MORE. WOW!!!!
