If you know which Blades you need to reorder, simply buy the number of Standard Blades you need. Once you get your order confirmation email, respond to it with the [code] x [the quantity of each Blade you need] in the comments field when you check out. For example: SC1 x 2, KW1 x 1, 1646 x 1
If you provide the Blade Codes, you will not need to submit a Key ID Form.
