I don't even take them out of the boxes, I never use them, but between 25-30, I've had way too many tanks , oh and just ordered a lemo v2, guess what will be in the box with it, yep another blue screwdriver lol
I have a pill bottle full of assorted screws, another one full of assorted o-rings and then a big on full of mini screwdrivers. Most are blue but I think I have one clear yellow, one orange and a couple of the black handled ones in there as well lol
