Small details I suppose, but I prefer to have the white label w/ clear printed part #s and descriptions. I bought some parts from the web shop recently and was disappointed to find hand written numbers on plain plastic baggies. Just leaves more room for error and makes you wonder why they are being so damn cheap. I mean US-made HK45s with NO markings on the slides? C'mon now, H&K USA, you're better than this!
The JF mag well kit has always come in a clear (but thick) plastic bag like what you received. The LEM and Match Trigger Kits are the same way. Having said that, all the springs, HK45C extended mag releases, Match sear springs that I bought 2 yrs ago from the HKWebshop, each came in their own HK branded little baggies.
The clear plastic is how they have shipped out parts for a while now to everyday customers like us. I believe you have to specifically request commercial packaging if you want it because I know they still use it when shipping items to dealers.
