Good Enough
Size: 500 Count (Pack of 1)
They are well built, with enough cotton on the tips. the stem is not as sturdy as the brand name, it does tend to bend with normal use, but it is well priced. Good product overall.

Simple Everyday Basic That Works Well – 5 Stars
Size: 500 Count (Pack of 1)
These are just good basic cotton swabs and honestly work just as well as more expensive brands I’ve bought before.
The tips stay together well and don’t feel super flimsy, and the big pack lasts forever. Simple everyday item but definitely worth buying again.

Value for money
Size: 500 Count (Pack of 1)
We reorder this item frequently. The cotton content is excellent and is thick. It doesn’t pull off easily. The quantity in the box is plenty to get our family of four through a month. If you have skin sensitivity, these are for you. We have sensitive skin in our family and have no concerns with this product. This product cleans well and the shape of the actual cotton tip holds well.

Repurchasing for sure
Color: Zero Pore Pads, Size: 70 Count (Pack of 1)
These toner pads have genuinely made my skin look smoother, brighter, and more refreshed. They’re super easy to use and feel really gentle while still giving noticeable results. My skin feels cleaner and softer after using them, and I’ve especially noticed improvement in texture and overall glow.
I also love that the pads are really saturated without dripping everywhere, and they don’t irritate my skin. They’ve become such an easy part of my routine, especially on days when I want my skin to look extra fresh and glowy. Definitely one of the better skincare purchases I’ve made lately.
