Any approach to purchase officialy this similar rubber analog thumb? Mine its getting "melted"

I like my starfield controller and already purchased a Cranium & Co grip to place above the analogs, however i needed to know if there’s a approach to get a official alternative for restricted version analog colours like this one (pink and gray) with out being a aliexpress decrease high quality one. Or if any larger model that makes high quality product and have a alternative for this.
