        Great value and super convenient for everyday use!
        Size: 300 Count
        exactly what I needed for busy days and quick cleanups. They’re sturdy enough for everyday meals like sandwiches, snacks, and even lighter hot foods without getting soggy or falling apart. I love the convenience of having such a large pack on hand — it lasts a long time and is perfect for families, parties, or meal prep days. The size is just right for most meals, and they stack easily for storage. For the price and quantity, it’s a great deal and saves so much time on dishwashing. Definitely a household staple I keep restocking!

        Great retinol face moisturizer
        Palmers always makes a great product in my opinion. This one's no different. It's a retinol that doesn't irritate my skin. I use a moisturizer below and on top. It absorbs quickly but doesn't sit on the skin. It's helped with my fine lines quicker than other products I've used and the price point is unmatched. Great product,not a strong scent, will continue to use.

        Very Good
        Why did you pick this product vs others?: I have been using this product for 2 days and can see a difference in the appearance of my skin. 40+ this does help with fine lines. I can already see my smile lines appearing less noticeable. A little goes a long way. You don't need to use a lot, or it will look like clown makeup, and you will have to work it in, but it is not a big deal. Also, if you have sensitive skin, I wouldn't buy a product clearly listed as extra strength. It will work as an extra strength product.

        Works but it takes time
        It does work but takes a few months to get results.
