I hope that this hasn't been covered before.
I tried searching for answers but couldn't find any information regarding this.
I bought a TWSBI Vac mini last week.
I disassembled the pen to take out the small o-ring at the bottom that acts as the shut-off valve.
I have seen a couple of videos to make sure I did it right.
Upon disassembly, I noticed that there was no o-ring (for the shut-off) at the end. The end of the rod actually looked quite different compare to the pics/vids I have seen.
In addition, I noticed that the Vac mini had metal parts (the part you use the TWSBI wrench) to instead of the black plastic that I have seen online.
I was just curious, is this an update that TWSBI has made?
