Where’s the best place to buy a ceramic case/bracelet for the AP × Swatch Royal Pop?

I’m looking to buy a white ceramic case and bracelet for my AP × Swatch Royal Pop and was hoping someone here could point me in the right direction.
I’ve found these two on Amazon:
£35: https://amzn.eu/d/0eMOPx88
£70: https://amzn.eu/d/02mYIrvM
The weird thing is they look almost identical, but one costs twice as much. Neither has any reviews, so I have no idea if the £70 one is actually better quality or if it’s just priced higher for no reason.
Has anyone bought either of these, or can recommend somewhere that sells high-quality ceramic kits with good reviews? I’m happy to spend more if the quality is genuinely better—I just don’t want to overpay for the same product.
Any advice would be appreciated!
