I was very surprised to see that the Gillette Sensor Excel handle(!) is still sold at Amsterdam airport.
For 9 but I think you can easily recuperate that with the less expensive cartridges.
The ones at Dollar General are the ones that Dollar Shave Club sells.What I like about the Dorco twin blades (at least the ones I get form Dollar General), is that they will fit both the Trac II and the Atra razors. One cart that can be used in a fixed or pivoting razor. Plus they are cheap and shave really well! (Better than Dorco DE, that's for sure)
I tried those before. I was traveling.Those are good enough to travel with
