Remington SP-42 XLR foil screen and cutter blade
These are the exact same parts you'll buy if you get them at the Remington Store.  They're packaged exactly the same, and last just as long.  I get great service out of these.  I replace them about every six to eight months.  Very durable.  And, you'll find them cheaper here than at the Remington Store.
