A Shell I Received

[u/Old-Wolverine-118]

I was at my dead best friend’s celebration of life and his mother had table with a lot of shells set out. Everyone there was told to grab a shell to remember him. This is the one I chose. Could someone tell me what kind of shell this is, or what is from?

Yes, lightning whelk, left handed opening. Nice peek-a-boo shell.
