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.

Starting a StartUp is a must-read for anyone who wants to build something that matters
Format: Paperback
I rarely come across a book that so perfectly balances the technical and the personal in building a startup. Starting a StartUp: How to Build Something People Want does just that. It is less of a textbook and more of a companion for founders who want to build with heart and wisdom. What I loved most: Actionable, no-fluff advice. Instead of lofty theories, the book dives right into what really matters: validating ideas, talking to users, iterating fast, and scaling smart. The checklists, templates, and real-world examples make it easy to move from reading to doing. Psychology + empathy. It does not treat an entrepreneur like a machine. The author emphasizes dealing with uncertainty, failure, and the emotional rollercoaster of starting something new. That human touch elevates it from “startup guide” to “founder guide.” Accessible to novices and veterans alike. Whether you are building your first side project or scaling your third company, there is value here: reminders about customer obsession, principles for experimentation, and stories that resonate at any stage. Readable and engaging. The prose is clear, the chapters are well-paced, and every chapter ends with key takeaways that help cement the learning. Starting a StartUp is a must-read for anyone who wants to build something that matters, not just for profits but for people. I am recommending it to friends, colleagues, and especially the next generation of makers I mentor. Highly, highly recommended. ⭐️⭐️⭐️⭐️⭐️
