Decent build quality, though the LED light is more of a cool white than the warm glow I was expecting based on the photos. It’s definitely more stylish than the Lutron equivalents I looked at, but the light output is slightly weaker than I'd prefer for a long hallway.

It's a good kit but just heads up you have to pay more for the lab testing once u send it in... still cheaper than some others i looked at though.

Finally a toner that doesn't strip my skin barrier! The ceramides and hyaluronic acid are exactly what I needed. It's a bit thicker than your average watery toner, more like a liquid essence. 10/10 would recommend for my fellow dry skin girlies.

This is my third Kipling case and the metallic finish on this one is gorgeous. It holds way more than 100 pens if you don't use all the elastic loops for every single pen. I use the bottom section for my bulkier markers and the top for my fine liners. It’s a bit bulky for a small backpack, but if you carry a lot of supplies like I do for bullet journaling, it’s a lifesaver. Plus the little monkey keychain is a classic touch.

It works but it blocks the rear AC vents slightly in my car. I like the extra pocket for my phone, but just be aware of the size before you buy it because it takes up some space.

As someone who loves miniatures, this is literal heaven. The tiny covers are so detailed and they look perfect in my dollhouse library! Definitely worth the hype if you're into the aesthetic.
