Dummy/pacifier with anti dust cover

AZ

My daughter is currently using the tommee tippee dummy which I clip onto her clothing. I’ve noticed sometimes it gets fluff stuck on it when putting it in her mouth so I have to rinse before giving it to her.

My MIL was telling me about a dummy cover which will basically stop any fluff getting onto it but I’ve looked in all of the shops and for the life of me can’t seem to find one... can anyone recommend a place to get hold of one please
