Septum ring

I got my septum pierced around 2 weeks ago, however I’m in the military and we’re not allowed to have them it’s very hard for me to flip it up and once I do it takes days to flip back down (have only flipped it once each way) I got a 18g ring and I’m struggling to find a clear retainer in the same size and I can’t find any at stores due to being stationed overseas if you know of any websites that are trust worthy place let me know. Thank you in advance!
