Preserving an owl pellet?

I got some insane shots of a Northern Pygmy Owl yesterday and didn't realise he coughed up a pellet right in front of me! I went back today and found the pellet. It's sorta gross but cool at the same time 😂 Is there any way to preserve the pellet so I can store it in a little jar? I considered dissecting it but I feel like this is probably pretty rare to find.
