Description
Nano 2nd Gen Pen Needles combine the shortest pen needle length embecta makes with a contoured base that sits flatter against the skin. The wider base spreads contact pressure, which helps users hold the pen steady and deliver insulin into the subcutaneous layer. A five-bevel 32G tip completes a design focused on comfort and correct placement.
- Contoured Needle Base – The reshaped base increases skin contact and helps reduce the risk of intramuscular injection compared with other 4mm posted-base pen needles
- Five-Bevel Tip – The 32G needle tip is cut with five bevels, and users in embecta studies reported significantly less overall injection pain than with other pen needles studied
- 4mm Length – The shortest embecta pen needle length suits most adults and children without a pinch-up technique
- Everyday Compatibility – Fits widely used insulin pens, so the upgrade needs no new pen platform
A Contoured Base That Coaches Technique
Short pen needles only work as intended when the needle sits squarely on the skin for the full dose. The second generation of this 4mm line adds a contoured base that gives the user clearer tactile feedback about placement. That contact helps keep injection force directed into the subcutaneous layer instead of deeper muscle tissue. The five-bevel tip geometry is ground to ease penetration, which matters for people injecting several times a day. At 32G, the needle stays fine enough for low injection force while holding its shape through the dose. Diabetes educators often start new pen users on 4mm needles, and this design supports that teaching with hardware feedback.
Features and Benefits
Base and Tip Design
- Contoured Base – A broader, reshaped hub increases skin contact to support correct technique and steadier placement
- Five-Bevel 32G Tip – Five bevel faces ease skin entry and were associated with less reported injection pain in embecta studies
Use Profile
- 4mm for Most Users – The 4mm length is the standard starting length for adults and children on pen therapy
- Thin Wall Flow – The extra thin wall design supports insulin flow at low thumb force

Why Choose the Nano 2nd Gen Pen Needles
Pen technique problems usually come from angle and depth, not from the insulin itself. A needle that gives the hand more feedback at the skin surface helps new and experienced users repeat a good injection.
- More Consistent Depth – The contoured base supports delivery into the subcutaneous layer, where insulin absorption stays predictable
- Comfort at Every Dose – Five bevels and a 32G profile reduce the tissue trauma that makes multiple daily injections wear on users
- An Upgrade Within the Same Routine – Unlike switching pen platforms, this change keeps the same pens and the same steps, only the needle improves
Frequently Asked Questions
What changed in the second generation?
The needle base was reshaped into a contoured design that contacts more skin. embecta reports the base helps reduce intramuscular injection risk compared with other 4mm posted-base pen needles.
Who should use a 4mm needle?
Most adults and children on insulin pens can use 4mm needles. The short length reaches the subcutaneous layer without a pinch-up technique for most users.
Does it fit my insulin pen?
It fits widely used insulin pens with standard pen needle threading. Proprietary pen systems remain the exception, so confirm with the pen maker when in doubt.
How many needles are in the case?
Each box contains 100 sterile pen needles. The case holds 12 boxes, which is the supply format listed here.
Can a needle be used twice?
No, pen needles are sterile single-use devices. Reuse dulls the tip, raises infection risk and can bend the fine 32G needle.
