I took these photos yesterday and popped it today! It's about the size of a pea. In one of the photos you can see a black dot, which is the punctum and is the giveaway that it's a sebaceous cyst. I gently pulled off the black dot and it just oozed everywhere! There's still a lump, but I expect it will go down a lot overnight. Was just hugely satisfying when all the stuff oozed out!
