Vermetid?

[swiss1939]

Black shell on the upside down people covered snail shell.. Thinking it's vermetid snails but want to confirm. I can see some fan or strands coming out the pointy opening of it.
My only doubt is that it seems thicker, larger and darker than expected for vermetid snails. It's a good eighth to quarter inch.

I'll just remove the shell of it is.

IF you meant "back" shell with "purple" on it, then it does look possible that it's a Vermetid. I'd just either toss the shell or pull it out, scrape it and toss it back in.
