Worth it! Solid dermaplaner.
Color: Matte Blue
It feels solid in my hand. The blade doesn't seem to be all too sharp, but it works... so maybe that's for safety purposes? I like it and will stick with it for a while.

Hair removal improvements, ooooh! Ahhhhh!
Color: Matte Gold
We were vexed and a little annoyed by that one chin hair removal after a waxing treatment. Lo and behold! Zomchi invented a razor for treatments in between salon wax strips. Painless and easy to reapply hygenically. 🤗

Handy. I've never put a razor to my face, but I used this and loved the outcome.

A real masterpiece
Format: Paperback, Format: Paperback
One of the best books I have read in years. A real masterpiece. I read most of it on a flight from Sacramento to NY and then forgot the book in a car from the airport to the hotel... I had to wait a week before getting a second copy, which I could not put down until 1:30AM when I finally finished it. I can’t wait for the movie. A wonderful story of the life of a startup that anyone in the industry can easily relate to. While many of us know the real story behind the true events, the book keep you in full suspense the entire time. I think the author has finally found his true calling 😉
