Afternoon all. I recently switched to Dorco after King Of Shaves discontinued the Azor 4. Dorco do 3, 4, 6 and 7 blade cartidges, four different handles and all interchangeable. I bought a tester pack with the 3, 4 and 6 ones in and like the 4s best. You can buy outright or do a subscription which is a bit cheaper.
They have a launch offer for the new website - whatever you put in the basket they'll ship double.https://www.razorsbydorco.co.uk/
Or if you feel especially thankful there's a referral scheme; if you use this link you'll get £5 off, and I'll get a £5 voucher when you order. If not just use the link above, it's not like I'd ever find out. http://razorsbydorco.refr.cc/andiallan
Be your own evil twin.
