I used the same thing but it was damaged and I purchased it again. I am using it for metal removal and sneaking. Long nozzle type L, lightweight for plastics, flowable OK !! Piston part is easy to use with prevention processing. It seems to be stronger than other products, but it is best if there is little strength. (The fulcrum near the fulcrum of the lever part was damaged last time.) This time we are reinforcing and using it.
