Double flares

I got some double flares recently and I tried to out them in but they would nooooot go in.

I’m at 10 mm rn and the ones I got said they were 10mm but no matter how much I tried to get them in, they wouldn’t go in. I would push (gently) but I had to stop because I didn’t want to tear my skin open from pushing too hard. Idk what to do, I want to wear fun gauges but the double flares I got don’t fit.
