Having just decided that red packs will be my go-to blade for the foreseeable future, I ordered 100 off eBay and received them today. When I compared them with blades I got from an online retailer (don't remember which at the moment), the packaging is different. I have an idea they may be the real deal, but knowing that the real sources of blades isn't always readily apparent, I thought I'd put this photo up for members to see & ask your opinion. Just a change in packaging? Packaging for a different market? Or something more devious? My original blades are on the left, new eBay blades on the right.
