From the descriptions they have under each set, it is clear that they are trying to be deceptive to a high degree. The ethics of clones aside if you go on aliexpress some sellers go out of their way to state that you are buying clones, while whoever is behind this store is trying their best to make their site seem reliable. They have a fake backstory and hired a copywriter to create fake descriptions of each set for seo purposes, this is super shady behavior. Even the "gmk" in their name is deceptive as it is an acronym for "gamer made keycaps", yet they only refer to themselves with that name once on their about page, not on the front page or description of their keycaps.
