Realistic fake septum jewellery

Sorry if this isn’t allowed here!

Hi, so I’m looking for a thicker gauge, realistic septum piercing that doesn’t use magnets. I have had bad issues with piercing healing in the past and bad experiences with terrible piercers. I finally got my septum pierced correctly, but couldn’t get a retainer in to change it for an mri brain scan. It was only 7 weeks old and the retainer I got just wouldn’t work out for me so I had a piercer just keep the jewellery out as my scan is Sunday morning and I didn’t have enough time to get a better retainer.

I want to get a fake jewellery at this point after the stress I have had finding a good piercer, that piercer being almost 3 hours away and that my health is very unpredictable and medical tests can be very sudden to happen. If anyone has any recommendations for good fake ones I’d love them. I’d prefer it to be in the UK if possible but honestly I’m willing to pay import if I can get a good fake that will be able to work for me. Thanks in advance!
