HTB1 brass for a smooth and shiny experience
The brass will naturally patina over time for a unique personalised look, but if you prefer the original look some metal polish and a lint free cloth will bring back the shine. D

The brass piston is a beautiful piece. Fun to play with, nice to look at. It has nice weighted feel in the hand. A little fragile but that is due to the low hardness of brass and to be expected. Therefore, If you are going to spring the rod out, ensure it lands on a soft surface and doesn't fall back and hit the barrel! I will be looking to purchase another piece in the near future, possibly the gears.

I ordered a MetMo mist on and when it arrived it didn’t work correctly. I spoke with the customer service team and they were extremely helpful (specifically Lindsie) they provided excellent advice and when it was apparent there was a defect in my piston they sent me a new one which works perfectly! 10/10

Item is very well made and well packed. It performs as I expected it to and I am happy with my purchase.
I think that if the outside of the barrel was etched with a spiral it would easier and more pleasing to see it spinning and if a spiral design instead of the concentric rings, could machined or etched to the top of the piston similar benefits would result.
