Fit my Dr. Pen perfectly!
I picked up this 21-piece microneedling cartridge set for my Dr. Pen device, and overall itโs a very solid value for at-home use. For the price (around the low $30 range), youโre getting a useful mix of 7 nano, 7 12-pin, and 7 36-pin cartridges, which makes it easy to switch between lighter skincare treatments, product infusion, and more intensive microneedling sessions without buying separate packs.
Compatibility was exactly as expected. The cartridges fit my Dr. Pen M7 securely with no looseness or alignment issues. They clicked into place properly and stayed stable during use, with no wobbling or skipping, which is important for a consistent treatment experience.
In actual use, the performance was reliable. The needles worked smoothly on the skin, and I didnโt notice any bending or breakage. Each cartridge comes individually packaged, which helps maintain sterility and makes them convenient for single-use sessions. The different tip types also give good flexibility depending on whether you want gentler nano-needling or deeper penetration with the 36-pin option.
That said, the build quality is a bit on the simpler side. The cartridges have a slightly plasticky feel and a blue-purple tint, so they donโt look as refined as some higher-end alternatives Iโve used. However, since these are disposable, that cosmetic difference doesnโt really affect performance.
Pros
Great value for a 21-piece mixed cartridge set
Includes nano, 12-pin, and 36-pin options for different treatments
Secure fit with Dr. Pen devices, no wobbling during use
Individually packaged and sterile for hygiene and convenience
Needles perform smoothly without bending or breaking
Cons
Build quality feels a bit lightweight and less premium
Plastic housing looks and feels cheaper than higher-end brands
Single-use design means ongoing repurchase required
Not much differentiation in โfeelโ compared to more expensive cartridges during use
Overall
This is a practical and cost-effective cartridge set for anyone doing regular at-home microneedling. While it doesnโt have the premium finish of higher-end options, it delivers where it mattersโfit, sterility, and consistent performance. For the price, itโs a very reasonable and useful refill pack for routine skincare use.
