The Lost Mary OS5000 vape device itself is 1 ¾” wide x 2 ¾” Tall x 1” thick. Out of the top, it has an oval-shaped mouthpiece sticking up ¾.” It has similar dimensions too and slightly rounded corners like a bar of soap. On top of the device is the slot for a type-C charger.
The flap that covers the charge port is hard to open. I see now why several of the devices I was given to test had the little rubber cover torn off. On top next to the charging port is a light that turns green for a full charge, blue for medium, and red for a low charge. At first, I thought the hole on top was the air input, but as I vaped it, I discovered it was the battery-level light. I am not sure where the intake hole is, but it provides enough airflow for a decent MTL (Mouth to Lung).
The front and back are covered in what looks like cheap colored plastic. The top, bottom, and sides are wrapped in a more durable matted plastic that gives it some strength. The mouthpiece is the same textured plastic and is easy to hold in your mouth with the mouthpiece. The texture has some grab to it and the mouthpiece itself is shaped well to fit your mouth.
