These are by far the most common model of disposable vapes I found in the past year.

Construction

The construction of these vapes is quite distinct. They have an easily recognizable clear outer plastic housing which includes the mouth piece. It is closed off by a metal cap. The actual parts of these devices live inside of the inner stainless steel tube.

Internals

The internals are nothing out of the ordinary. They consist of a liquid container, a battery, and a controller embedded in a silicone grommet.

Liquid container and coil

The internals of the liquid containers are exactly the same, except for one detail. The wires to the coil in the SKE Crystal Bar go through the silicone grommet, where in the Vapeurs Crystal the wires are connected to dedicated solder tabs which are embedded in the silicone grommet.
