Good Variety Pack With Solid Compatibility, But No Protective Caps
This is a review for this 21-piece variety pack of Dr. Pen microneedling cartridges. For around $32, this actually feels like a pretty solid value overall. You’re getting seven nano cartridges, seven 12-pin, and seven 36-pin, so it’s a nice mix depending on whether you’re doing product infusion, lighter treatments, or more intensive microneedling sessions. I always appreciate a variety pack because otherwise you end up buying giant boxes of one type and suddenly becoming emotionally committed to 36-pin needles for the next six years.
These fit my Dr. Pen M7/M7S perfectly with no issues clicking into place or staying secure during use. I didn’t have any wobbling, uneven dragging, or weird skipping while microneedling. Functionally, they performed just as well as other replacement cartridges I’ve used.
That said, they do look and feel a little cheaper than some other cartridges I’ve purchased before. Not necessarily unusable, just not quite as sturdy or polished-looking. Since these are single-use anyway, that may not matter to everyone, but it was noticeable.
My biggest hesitation is that these do not come with protective caps over the needles. To be fair, the listing photos actually do show them packaged this way, so it’s not misleading — they were honest about it — but personally I’m just more comfortable when cartridges have caps for an added sense of sterility and protection. They are individually vacuum sealed with expiration dates, which I do appreciate, but I’ll probably use my capped cartridges first before reaching for these.
Because of that, I’d feel a little more comfortable initially using these on areas like the chest or neck rather than jumping straight into facial treatments, at least until I’ve tested them more thoroughly. I’d also definitely be extra cautious about sanitizing everything beforehand.
Overall though, for the quantity and variety included, this still feels like a decent buy if you go through cartridges regularly.
