TBH I was skeptical because of the brand name but it's actually really decent quality. Not as plush as the one I saw at West Elm but for a fraction of the cost, I'm not complaining.

It's okay, but there was a weird chemical smell for the first few days that kinda bothered me. It's comfortable enough, I just don't know if it's worth double the price of the generic stuff you find at big box stores.

Honestly way better than the cheap files I was using before. The diamond edge really makes a difference on my labs thick nails and doesn't just dull out after two uses. Definitely worth the extra couple bucks for the quality!

It does the job but the magnets aren't as strong as I hoped. If it's even a little bit windy, the screen blows open and stays open. For the price it's fine, but don't expect it to stay shut in a storm.

Better than the ones I saw at Hobby Lobby and way cheaper. The vintage colors are muted and classy, not bright or neon. I’m obsessed with the font choices!
