It’s discontinued and so thus are the “official” capsules, but I’ve had no issues with the no name brand argon capsules on Amazon (cheaper also!) which screw right in and work great.
It comes with:
-Preserver
-2 Closures
-Display Stand
-All the argon capsules I have remaining (currently 4 “official” branded wine enthusiast ones and 3 no-name)
$75 shipped anywhere in the US
