I really like this product!
Color: Collagen
I tried these eye patches that stick right under the eyes, and overall they’re really convenient and easy to use. They adhere well to the skin without sliding around, which makes it simple to wear them while relaxing or getting ready. After using them, my under-eye area felt more hydrated and looked a bit brighter and less puffy. The cooling effect was also soothing, especially when I kept them in the fridge before applying. They didn’t cause any irritation, which is a big plus for sensitive skin.

Great half wig
Color: Off Black 1B
I buy this wig like clock work. Its really cute and everyone swears its my hair. It does get tangled and starts to get puffy really quick but I do wear it like its my hair all day and take off when I'm home I also use it when working out so I do get it kind of sweaty but for the price this hair is worth it. I buy a new one almost every 2 weeks or so. This is a great inexpensive wig.

Outre synthetic quick fix
Color: Off Black 1B, Color: Off Black 1B
Sooooo cute, got so many compliments. Only knocked off a star bc i thought the curls were going to be a bit tighter. I added some moose and it actually loosened it up and looked even better, so yay! Easy to install, but my head is kinda small so regardless of me tightening it, it was still kinda loose.
