Regarding 6th yeard B'day presents

So i logged on after a couple months break to discover I have around 4 6th year b'day presents across my characters and was curious if anyone could tell me if its maybe worth opening all of them or selling them unopened? How manys tonics are there actually out there that are worth over 25e?

Thanks in advance for any help.

It's really your choice on whether to open them or not. Go to the wiki and type in everlasting tonic. On the bottom it will show the 6th yr tonics. The greens are worth way more than 25e, and some of the golds are as well. Watch kamadan trade chat to lean the values. In the end its up to you.
