seal broken

I've got some old T5 bulbs that have been in storage for possibly over 10 years, and some of them might not have ever been used. I want to use them now but am concerned that the seals keeping the mercury vapor inside might be compromised after such a long time. Any thoughts?

NLS has an outer plastic lid which you open, then inside there's a paper seal that your supposed to rip off. The plastic lid was tightly closed. When I opened it, the paper seal came off with the plastic lid. Is it still safe?
