I just found this London-based tailmaker on Instagram. (https://www.instagram.com/sikiredfins/?hl=en)

He seems to have a lot of really interesting products (for example: extended tails, completely transparent/translucent flukes, organic-looking mergloves that give you webbed fingers, etc.)

I was just wondering if anyone else had heard of this company or had any experience with them, because I must admit, I am entranced by those see-through flukes and am considering purchasing! (I do worry a bit about how loose his tails appear to fit sometimes, though.)
