Type 1 Insulin pens recommendations

I have been using an insulin pump for 6 years , I have been advised that I need to replace my insulin pens as mine are very old at least 10 years , I use nova rapid although very small amounts , I have no idea what pens are available, I prefer pens that are not prefilled as there is a possibility that they will expired and will be thrown away . I used to use Levermir as long acting insulin . I am a very long distance from my diabetic team but my local GP will happily prescribe pens if I tell her which ones , I used to use pen with 1/2 units and was also metal although a bit boring but did what was needed , have pens changed ? And what could anybody recommend and why they like the pens they have ,TIA Nicky

Both really helpful , I had my app with DSN who told me my pens only have a life of 5 yrs max and I need to replace the old ones in case pump fails etc but she didn’t know what pens to recommend but to see my gp who will prescribe new ones . ARGHHHHH ! but as a person she is lovely
