The tumbler is 4/5 good at retaining heat or cold and handles all my drinks from monsters to black coffee. The minus one star is due to the design of the lid its really hard to open either some rubber material or serrations like on a glock would help in opening
Blackbeard Tumblr is an outstanding product I highly recommend you get one 🤘🏿💯🇺🇸
This mug is the sh** . Fill it up every morning around 845 go to work and sip it till about noon. Keeps it warm the whole time. Plus it looks bad ass. Also the afterlife coffee is good as f**k
Recomendando 100%, material de muy buena calidad.
