I included some pics to see which size Thermos jug I have, which I think is around 24ozs or so, since I don’t know which exact model I have. For some reason I lost the darn seal in the process of washing it all and setting on the rack. It wasn’t the 1st time I dropped it without noticing until I reassemble it for use. I always found it nearby on the floor or the drying rack. This last time, I couldn’t find it anywhere and for weeks I couldn’t use it.Thanks to Amazon, I was able to find something that worked. While going through the reviews, someone had mentioned that it worked on certain style Thermos containers, but there’s no model # on mine. It’s been a few months now, and have had zero complaints.
