Unifine Pentips, 31G x 6 mm, 100 per box. A mid-length needle from Owen Mumford — the middle option between the very short 4 mm needles and the longer 8 mm ones. Specification Gauge: 31G Length: 6 mm Quantity: 100 per box Fit: universal screw-thread, compatible with most insulin and injectable pens Sterile, single-use, individually sealed Where 6 mm sits Needle length is not a one-size-fits-all decision, and 6 mm remains a common choice — particularly for people who've used it successfully for years, or where a practitioner has specifically recommended it. With a 6 mm needle, a skin fold or an angled insertion is sometimes advised depending on the injection site and your build. If you're not sure whether 6 mm or 4 mm is right for you, ask your pharmacist or diabetes educator before you switch. Getting this wrong means injecting into muscle instead of fat, which changes absorption speed — with insulin that can matter significantly. Standard practice One needle per injection — reuse blunts the tip and increases infection risk Remove the needle from the pen after each use Rotate sites to avoid fatty lumps and keep absorption predictable Hold for roughly ten seconds before withdrawing to deliver the full dose All used needles into an approved sharps container — return full containers to a participating pharmacy for safe disposal Also available We stock Unifine Pentips Plus (32G x 4 mm) if you'd prefer a shorter needle with a built-in removal aid. Store at room temperature in the original packaging, away from moisture, out of reach of children.
