Congrats but first things first, is it the pbt version? If so, you're gonna have a hard time removing them since the legends are infilled.  mine are yellowing too but they're thick pbt so there's that.

It's either you go all in and invest on good end game caps once and for all, or if you just want something which is not yellow, then you can go ahead and buy some cheap caps.

I bought one cap similar to those selling at heavy-arms, they aren't that thick, some of the caps are actually very tight, make me think twice when I wana pop them out, and worse of all, some of the caps aren't aligned in the center, you can see that after you pop them in, they are slightly to the left or right.

Good thing about them is that the colors are nice and it's cheap. Not sure whether it's problem with my batch or all of it also like that. >.<

If it's thick pbt, you might want to continue using them instead of getting the tai-hao thin double shot abs available at heavy-arms.
