The OSMALL 2 is still very small and very light, just like the original. The dimensions are also nearly the same and the OSMALL 2 is just 86.8mm tall, 26.5mm wide, and 13.5mm thick. It’s very small and handy and definitely remains true to the OSMALL name. When you look at it, you can’t help but say “It’s so small”.  
A complaint that I had with the original was that it was made of plastic, but the OSMALL 2 now seems to be made of aluminum alloy. This case feels much better constructed and even though it’s so light it feels much more solid. 
There are 7 colors available: green, blue, gold, pink, silver, grey, and black. All of the colors have a metallic finish that is, again, much nicer than the plastic finish of the original. Another change from the original OSMALL is the finish on the casing. The OSMALL 2 has a “water ripple design” which is a textured pattern of raised “ripples” on the front and back of the device. It looks good and also adds some grip to what would otherwise be a slippery device.
On the front of the OSMALL 2 there is a small metal plate with an LED. There is also a VAPORESSO logo and “OSMALL 2” printed. The white LED lights up every time that you take a draw. The OSMALL 2 is draw activated; just inhale through the mouthpiece to start vaping.
