Golem Gear/iQsub GoPro Housing O-Rings Size

[GF99/99]

I was wondering if anyone knew the size numbers for replacing the O-Rings for a Golem/iQsub GoPro housing. I have the 9/10 300m version but from what I can tell they are all the same 2-9 Replacement o-rings for Golem GoPro housings. Also I emailed Jakub about the size but they would not share, just sent me a link wanting $24.15 for some $0.50 o-rings.

I just struggle paying $9 + $15.15 for regular USPS snail mail (when i know they would easily just fit in a regular $0.60 envelope)

Plus I am about to order a big bag of DIN o-ring and SPG o-rings from theoringstore.com so if I would love to just add these onto my order since I know its probably only about $0.50 max for the GoPro housing o-rings.

Measure with calipers perhaps? Could also roll up a sheet of paper inside of it, try to ensure it’s straight, then trace it and measure.
