Oh right. Same goes for me. I've been looking for that for quite some time, but after I got the treasure, I got another two which I don't really use :(

Also the princess bee royal jelly (extra 170 health in relay) is also helpful in certain situation. I guess you should keep that as well.

I've opened a big set just now. I got 5 S-grade treasure, but none which I liked.
