Hello, I'm from Canada. When can I receive it if I order this?
This is an "interest check", it's not a product you can order at all. Spritu, who created this thread, WANTS to produce this keycap set and is looking for other members of the community to join him. To mass produce something like this requires at least usually 100-250 people join him and sign up in advance to buy the set once it completes.
After and if that happens, then it can take 6 months to 3 years before the keycap set is actually delivered.
But the production partner he wanted to do business with to produce this set ("KBM") is - as far as I know - now defunct anyway, so there is zero chance at the moment you will ever be able to purchase this.
Spritu can change and cooperate with a different manufacturer, but that's their choice.
