Review (5/5): If you’re new to DE shaving this is a great sampler to start with.  Did take 2 weeks to arrive.
I’m still working through this pack with my Edwin Jagger long handle DE89. It’s giving me an idea of what I like in a razor blade. I only had 5 Derby blades that came with my razor prior to receiving this pack. I did end up buying more Derby’s as my go to blade while I try these out, but only after trying a few other brands from this pack and finding that the Derby’s work really well for me with my razor. Plus they were on a really good sale on amazon. I have found one other blade in this pack that I would definitely consider buying in bulk, but it’s very much an individual style/particular razor based choice. One thing you should be aware of is that it ships from Germany, so it takes about 2 weeks to make it to the states. At least it did for me. I highly recommend that if you’re making the investment into a DE razor that you order this immediately. By the the time you work through the blades that came with the razor, you should get these.
