I bought this and #12 drilled rubber stopper, BUT #12 was little bit small for this. Because inside diameter is not 2.25", it is 2.36". #13 drilled rubber stopper is suitable for the one I got.
Or you should buy a rubber stopper after you get this flask...

Had one that lasted for 6 months of continuous use (which is fairly reasonable), but then I had some really poor experiences. Got one that cracked on the bottom weld during the first time under vacuum. Had another crack in the same place after a little use. Got a replacement that was packaged with no padding and a torn box, so that went back because it wasn't worth the risk, and even got a replacement which was actually the exact same cracked one I sent back in originally! At this point Amazon pulled the remaining ones from the website and ordered a new batch. I opted for a refund.
These are a great price, but my glass blower friend says they must not have annealed this batch properly.
