I’ve been looking at these pen bags for some time and finally got round to buying one. The bag will hold 2 pre-filled pens and even squeeze in a couple of needles. No room for a cooler pack but leave the bag in the fridge before use to help keep the pens chilled to start with. Very happy with my purchase.
Looks to be a good stylish bag. Have not yet used it but I was amazed that I order it 3.30pm and arrived by post next morning on a standard delivery. WELL DONE.
