Ah, welcome to the business of keycaps! Here, we specialise in maknig money, users be damned. To start, the first thing we should do is make a keyset. How do you do this? Who gives a ****, colors don't matter to the sheeple. Throw random colors on a set and bam, instantly you're getting profit. Ever seen GMK Handarbeit? Just proof that no one cares about these things! Next, you have to find a vendor. Well, you normally would, at least. But since we're a savvy businessman, and vendors would take some of our profit, we can just do this all on our own! "But Mangoes," you say, "don't I have to build trust first?" Nonsense! No one pays attention to that ****. Just sound like you've been here for ages! Talk about the good old times, remind people that artisans used to be cheap when you first started, or that OEM is the only real profile. After this, you just have to ship them out! Or don't no one expects these things to actually be sent to them anymore anyway! Just sell more than you actually make and let the rest "get lost in the mail" and once you say you're sorry, you'll just become a meme and no one will care anymore!
Remember, you're here to make money! Just throw some caps into a strangely designed box, I can guarantee you'll make money no matter what!
