Request for good razor brands!(r/BuyItForLife)
get a double edged safety razor, merkur is a good brand for the price/quality. you can get blades by the hundred pack for less than $20. astra & personna are pretty good. you can get variety packs of blades & decide which brand you prefer. even “expensive” double edge blades are significantly cheaper than cartridges.
