Good but not great purchase
Color: 02 - Antique White, Size: Queen, Color: 02 - Antique White, Size: Queen
The sheets are soft and fit the bed amazingly!! Downfall there was a rip in the fitted sheet at one seam. I had to mend it myself as I had to have a sheet to sleep on and a return would take too long. Also a few pieces of thread not properly secured. I am unsure if I will buy again but the pros are: Clean packaging Soft Comfortable

Perfect Teacher Water Cup for Long School Days
Size: 40 Ounces, Color: Rose Quartz 2.0
As a teacher, I carry this with me constantly, and it’s honestly been one of my most-used purchases. The 40 oz size is great because I can fill it once in the morning and not constantly worry about refilling it throughout the school day. It keeps water cold for hours, even when it’s sitting in my classroom all day, and the handle makes it much easier to carry along with everything else teachers somehow end up holding. I also like that it fits in my car cup holder despite being large. The straw lid is convenient for quick sips during class, and the Rose Quartz color is really pretty without being too flashy. The cup feels sturdy and well made, and it’s held up well to daily use. The only downside is that when completely full, it can feel a little heavy, but that’s expected with a large stainless steel tumbler. Overall though, it’s been incredibly practical for staying hydrated during busy teaching days. Definitely worth it if you’re someone who’s constantly on the go and wants cold water all day.

Love the Color and Keeps Drinks Cold for Hours!
Size: 40 Ounces, Color: Pomelo
I absolutely love this tumbler! The first thing that caught my attention was the color — it’s even prettier in person, and I’m obsessed with it. It has a great look and makes carrying it around fun while still being practical for everyday use. Beyond the color, it works great too. It keeps my drinks cold for hours, holds plenty of water, and helps me stay hydrated throughout the day. The handle makes it easy to carry, and the straw is convenient for sipping on the go. It also fits nicely into my daily routine, whether I’m at home, working, or out running errands. Overall, I’m very happy with this purchase. The color alone had me sold, but the functionality and quality made me love it even more!

Favorite Stanley
Size: 30 Ounces, Color: Mahogany Gloss
This Stanley is my favorite for on the go. It keeps my drinks cold and fits snugly in my cup holder. I love the straw for ease in use so it won’t leak. Very durable and easy to carry. Love the color.

I see why the ladies go crazy for these 😂
Size: 40 Ounces, Color: Peony, Size: 40 Ounces, Color: Peony
Bought this for my daughter as a ten year olds birthday request. She wanted pink or purple in 32 or 40oz that’s it but being me, I figure she needed some stuff to go with it 😆! It was $45 for the 40oz Peony Pink color. I thought the lilac was also gorgeous but this pink stood out so strongly and in stores they only carry the hot pink 40oz that has an orange logo on it. I don’t think it’s as attractive as the one o bought and I don’t think she enjoys orange either. It’s sturdy and sleek and comfortable in the hands. The screws were standing out so heavily as fine quality upon notice. No scratches or scuff. Super clean. No Oder!!! Thank God!!! I hate strong oders. It does have gaps where you can easily see it’ll leak if it’s full and you tip it over but being the dad that I am i bought the stoppers as well and they fit so snug. Could still leak but it’s not supposed to be upside down so like… who cares? And seriously you really have to work hard at getting it in a position that causes it to leak. The stoppers I bought for snuggly so I’m very satisfied with the leak stoppers I bought on Amazon, I left a video of the before and after installing them in the other sellers review section. I would know how to link this one to that one but hope you find it and that it helps. But if you don’t buy the stoppers, Honestly get over it nothing is literally perfect except Jesus so just enjoy the cup, it’s phenomenal even without the stoppers. The stainless steel or titanium is what it actually looks like is superb by the look and the feel!!! The pink paint is gorgeous!!! Taylor Swift probably made that song about this Stanley 🤷🏾‍♂️ I seriously wouldn’t be surprised. I have no cons for you honestly. It’s a wonderful buy and I get it now why she wanted one and why my girl friend also desires a Stanley. I really questioned why that brand of all brands like it’s just a cup, like it’s not that serious?! 🧐 but low and behold! Boy! It is that serious and for the price amazing and again, I could not find this color anywhere in the real world. So thanks Amazon! Thanks to the seller and thank you Jesus we have the internet and apps that make life easier for everyday day citizens like you dear reader who took the time out to read my long winded commentaries 😂. Hope this and the pics and videos help you making your decision. I’m fully intending to buy one for myself in some bold manly color if I can find one. If your worried if it’s fake or not, you can compare them to the others online: #1 Screws are located underneath the handle and are aligned well. Using the same metal as the inside of the drinking canister which is really think is titanium and not stainless steel actually. Because it’s definitely superior grade quality. Trust me you’ll know the difference looking inside it 😆 #2 the straw comes in the cup already with no separate packaging and is the same semi-cloudy tone as the upper lip of the cup and is not totally transparent or translucent. #3 the inner canister of the metal bottom will have an etched in recycled sign at the very bottom. #4 the Lion logo on bottom of cup. #5 the Lion logo on upper half of the cup will be about an inch or so from the lip of the cup while a fake will be two to three inches lower, much further from the lip of the cup. #6 the top of the cup handle will be super close to the top of the stainless steel part while a fake will be noticeably further from the top of the top (like inches or so away from the lip of the cup). So this one is real! And I highly recommend it!
