Handy tool 'holster'
Allen Wrenches are improperly sized for some markers.
Well, I got this for Christmas as a stocking stuffer. This was the first time I've ever had all the tools necessary to COMPLETELY disassemble my marker. After removing my macro line, drop, neck, and removed the grip covers however, I realized the only problem I've found with this thing. None of the allen wrenches fit in either of my bolt sizes. At first I was really pissed, but I still had the original allen wrenches that came with the gun, so I was alright. I suppose other markers probably use different size allen bolts, but I really am not quite sure about this. Everything else this thing came with worked great, and I got mine for sale ($20), so overall I think this was totally worth its cost.
If you're lacking any tools to COMPLETELY DISASSEMBLE your marker, this is a MUST! If you buy one and the allen wrenches don't fit, just get a real hex-key set or look for the ones that came with your marker.
