look at the stopper face for a dimple or a needle track. a vial that has already been entered will often show one
press the centre with a thumbnail. it should be firm and spring back. tacky or hard means the elastomer is off
then look at the cake edge against the glass. a clean puck with a defined edge is a good cycle. a smear up the wall is not
and if the crimp spins
photograph it, weigh it, email the vendor before you open anything. once it is open you have no case
that last bit is the useful one
