This Aladdin thermos has been in six states on many construction sites and carries plenty of dings and scratches to prove it. This thermos has seen 4 story red iron, custom home construction in the winter, DEC computer clean room, family fitness spa construction, 4 story mall in Colorado Springs, jeez, I better quit before I keep it. I'm an old guy now...
The No 11 stopper seals perfectly but is broken on the edge as shown in my pic.
This is the thermos of a journeyman not an apprentice. A solid thermos that will NEVER let you down!
