Strong, Spacious, and Perfect for Every Meal
Style: 34 Ounces, Size: 34 Count
I’ve been using the Dixie Ultra Extra Large Paper Bowls for a while now, and they really stand out. With a 34 oz capacity, these bowls are big enough to hold hearty meals like soups, stews, and even large salads without worrying about spills. They’re perfect for heavy meals or when you just want a generous portion. What I appreciate most is that they’re compostable, which makes me feel better about using disposable products without harming the environment. Plus, they’re microwave safe, so reheating leftovers is super easy and convenient. The bowls are sturdy and don’t get soggy or flimsy, even with hot or liquid foods, which is a huge plus. Whether you’re having a casual lunch, a family gathering, or need something reliable for everyday use, these bowls deliver both quality and convenience. They handle big meals with ease and clean-up is a breeze. Definitely a smart choice for anyone who wants disposable bowls that actually hold up!

Very smooth and also affordable when buying the 3 bottle set.
Scent: Unscented, Size: 20.3 Fl Oz (Pack of 3)
I just love this lotion. I am 78 years old and need extra moisture daily. I can tell you how this lotion has made such a difference in my mature skin. I use it every morning after a shower and nightly for over night protection. I love that it's unscented and doesn't take away from my cologne that I love, where other lotions overwhelmed my cologne. Anyway I love it so much that I bought the 3 bottle package to have it always on hand. I am very picky with my face lotions and serums and I use this lotion on my face after my serums. It makes my makeup go on so smoothly and seems to help not having to reapply during the day. I just can't say enough about it and this lotion will be my go to body lotion as well. I am constantly getting compliments on how soft and smooth my skin looks and feels and this is saying something when approaching 79 years young!!!
