Oil Filter O Rings

Hey, I’m a recent Hyosung owner and bought an oil filter (HF681) for my 2014 GT650 without realising it didn’t include O rings. I’ve looked online and it would cost me a ridiculous amount to import these.

Are these O rings a standard size and am I able to get them at your typical auto store?

Thanks
