Best disposable razor ???????????
I've been on Schick tripples.
They are $2.88 for a five pack, but are frequently in "bonus" 8 packs for the same price.
I swear by Edge gel for sensitive skin (purple).
The razors have been lasting about a month to two months.
If you can remember to dry them, they can last a lot longer.
Think about a bare metal surface and water evaporating and oxidation.
