stopper are to large should have incremental size not small medium large
I have picked up in the past large stoppers thinking these were right .your mediums I expected to be proper size there are large and if you treat should give a dimension

My plastic carboys have almost the same size opening as the bottom diameter of these stoppers, 1.68", are they flexible enough to fit well?? Thanks!

BEST ANSWER: Yes, I use it on a 5 gallon water jug. It fits just fine.
Will this fit the 1000 ml Erlenmeyer flask since the site doesn't offer the recommended no 8.5 stopper?
A shopper on Jun 23, 2017
BEST ANSWER: The small universal stopper is the item that will fit in our 1000 mL Erlenmeyers.
