Product Introduction
The Hall speed measurement code disc is a speed measurement module that utilizes Hall sensor encoders. Equipped with a strong magnetic disc, it generates AB phase output pulse signals, enabling the detection of motor rotation direction and speed. It is suitable for various intelligent vehicles with high-speed requirements, such as Mecanum wheel vehicles, balance cars, navigation positioning vehicles, etc.
Wrapped Rear Tail Shell
The motor features an wrapped rear tail shell designed to provide robust protection for the PCB circuit and magnetic ring, shielding them from external influences. This design enhances safety and extends the overall service life of the motor.
Permanent Magnet Brushed Motor
The permanent magnet DC motor offers rapid response, startup torque, and smooth shifting. These features eliminate vibrations during speed changes from 0 to the maximum, enabling it to handle larger loads during startup.
Suitable for Various Scenarios
With a 1:20 ratio, the low-speed configuration matches a 1kg.cm torque, allowing the motor to adapt to a variety of chassis materials and diverse scenarios.
Durable Metal Gear
The motor incorporates a full metal gear and metal output shaft, reducing power consumption and extending the motor's service life.

INACCURATE DESCRIPTION
Style: Dermaplaning Oil, Style: Dermaplaning Oil
the product description reads, “ Dermaplane Oil for Smooth Razor Glide, with Squalane & Vitamin E, Face Oil for Dermaplaning Oil, All-Natural Formula, Dermaplane Spray Oil, Non-Greasy, Suitable for Sensitive Skin 3.21 Fl Oz by MyMed”
However, the product I actually received is one box of 1.7 fl oz. Not worth the hassle of returning. Just want others to be aware of the product error.

Silky smooth for dermaplaning
Style: Dermaplane Oil
This is a very effective dermaplaning oil that isn't greasy and allows my razor to glide over my skin smoothly. After use, my skin feels better hydrated and smooth. The ingredients are natural and good for the skin, and I've noticed a difference when I use it. I highly recommend this natural oil for dermaplaning.

Wonderful but Sharp!
Size: #14R, Style: Pack of 20
These things are legit! This is not the typical ones you find in Walmart, Ross, TJMaxx etc. This is a true blade that will indeed do authentic dermaplaning. That said, be EXTREMELY careful with this as you can easily cut yourself. I highly recommend to anyone experienced but if you have no experience I would opt for the typical ones you can buy in the stores previously mentioned.

Professional-Quality Scalpel Blades for Dermaplaning = Clean, Precise & Individually Sterile
Size: #10R, Style: Pack of 10, Size: #10R, Style: Pack of 10
I’ve been using these sterile disposable scalpels for dermaplaning, and I’m honestly very impressed with the quality especially for the price point.
Each blade comes individually packaged and clearly sterile, which is extremely important for both professional and at-home use. The blades are sharp, precise, and glide smoothly across the skin without tugging or causing irritation. That clean, controlled edge is exactly what you want for effective dermaplaning.
What I also love is the consistency every single scalpel in the box performs the same. No dull blades, no inconsistencies. The handle feels lightweight but still easy to control, giving you a steady grip during use.
These are perfect for:
• Dermaplaning
• Precision skincare treatments
• Light professional use
If you’re someone who values hygiene, sharpness, and reliability, these are a great find. I’ll definitely be repurchasing.

The softest skin you will ever have without any expensive products!!
Great for removing dead skin and peach fuzz. A lot of other blades have the little teeth that are great for preventing scrapes and cuts but don’t quite get close enough for me. You do have to be careful because they are very, very sharp and you can cut yourself. It does have rounded edge that is very helpful in preventing the little cuts. My skin is super smooth and my makeup goes on amazing after using. As a 47 year old that makes a huge difference.
