The Blood Crystal color is a virtual match for the Pokemon Ruby game cartridge shell. These have the same feel from OEM buttons to me. The A and B button seem ever so slightly rougher to the touch than OEM buttons, but that could be that OEM buttons I've experienced are rubbed smooth from years of use.

arrived quickly. great quality

I bought the blood crystal buttons. Most of the buttons were great quality, but my only gripes were with the shoulder buttons and the power switch.

In my pictures, you can see that the left shoulder button was not made correctly as it leaves a small gap on the bezel of the GBA. The gray shoulder button is an original part and it covers the space between the shoulder button and the edging, whereas the blood crystal one does not.

And the power button seems to be a bit larger than the original part. Because when I had the blood crystal power switch installed, I had to use an immense amount of force to flip the switch.

Look great, easy to install.

If they have the color you need, then go ahead and grab these! Great replacement buttons for a variety of color themes!

The buttons look great, but I really had trouble with the L + R buttons. The L shoulder button specifically would constantly keep sliding out and then the spring just came off. I had no trouble with my OEM shoulder buttons but I didn't want to use those. Maybe I just got a bad spring.
