Not trying to bash you. But I want to share with CSers on how to spot fake bags. It is not very hard after you know the details. First let me start by saying what looks out of place in the pics of the bag you showed.
The plastic bag packaging is a hint but not a dead giveaway. Most bags are packed with the logo on the plastic bag matching the orientation of how the actually bag is to be seen. This means the crumpler logos on the plastic bag should be upright, it is turned 90 degs. Also, the barcode product ID sticker is missing.
Look at the center seam going down the front flap of the bag. Where the seam ends is not exactly the middle point of the flap.
You mentioned it yourself, the logo is slanted. And the logo should be sewn with white thread and not black. This is one of the dead giveaways. And the logo looks a little rough on the top inside(can't be sure due to bad picture).
This is the other obvious giveaway that this is a fake. The Logo stitch on the shoulder pad is very badly done. There is this big Dot thing on the top right corner of the logo with a connecting thread to the "face" of the logo. That is very sloppy embroidery work. This is the dead giveaway. One look at this and I am 100% sure this bag is a fake.
Looks real with the logo and all. Do not get fooled, it costs a few cents to stamp these zipper pullers out. And the original one do not have a logo there.
This is another dead giveaway. "It is not properly sewn" is an understatement. The edges of the tags are sewn very untidily. The wordings are sewed over.
I keep seeing the word factory defect popping up over and over again. Yes, there are some factory defects from time to time. But do know that there are very seldom instances where the factory has defects in multiple places of the bag. If you spot MORE THAN ONE defect, red flags should pop up in your mind already. If you spot 3 or more defects in different areas of a bag, you can conclude it is a fake (and you will be right 99% of the time).
Also, certain things, defects are just not possible. Like the logo stitch on the shoulder pad, you have to understand the process. The stitch is programmed into the machine, which will do stitch after stitch after stitch without room for error. If such low level errors happen, it cannot be a defect from the factory. It just means it is done in another factory (not crumpler's OEM factory - aka fake).
And Clarenze, kudos to your positive attitude. Just be careful and not get ripped off in the future. This bag costs less than USD$10 to make.
