Well, that's just say that a couple of weeks ago, some people on /r/mechanicalkeyboards noticed a particularly good-looking deal on several sets of Keycool PBT keycaps. And when I say good deal, I mean ~$25 for a set of 104 caps. Seeing as this company (abbreviated BG) is from China, some were skeptical about whether or not this deal is legit. However, they are branded as Keycool keycaps and apparently LinusTechTips did a review of this site, so it would seem as though the deal is in fact legit. mkawa and I exchanged several PMs and he basically swears by the fact that this site is a scam, but I don't believe it. He said they used to be known as Tmart, who to be fair have terrible reviews on resellerratings, but BG has a 9.3/10 and there's no indication to me that it's a sketchy site. Side note: mkawa also said that BG has spammed advertisements on GH and even offered bribes for business, but I'm simply trying to take advantage of the wonderful capitalist market that is the internet. I'm clearly not a spammer or affiliated with BG in any way. Now, I know of plenty of people on /r/mechanicalkeyboards who have purchased these caps. Although I don't think anybody has received them yet, they are in transit and the company stated up-front that delivery could take several weeks due to customs. So I don't think I'm being too naive when I say this deal appeals to me.
Anyway, on to my question. The keycaps I want are gray and are listed as "Keycool 104 PBT Grey Laser Etched Keycap Laser Engraving Key Caps" on the site. You definitely shouldn't google that text because then you might find the product page. I'm very confused because it says laser etched but it also says laser engraved, and I didn't think that was a thing. Laser etched or engraved, but not both. I don't want engraved because dirt gets in the engravings. Now, also listed on BG is a product called "Keycool 104 PBT Top Print White Key Caps for Cherry MX Switch." Notice it says top print but there's no mention of engraving. Now, one could logically assume that these keycaps are the exact same set in different colors, but I don't think that's the case. KEYCOOL is clearly visible on the gray spacebar, but you can't see it in the white spacebar and someone on reddit who already received their white keycaps said there's no text on theirs. Also, the gray set has one Windows key and one Fn key, whereas the white set has two Windows keys. So even if they're similar keycap sets, they're not exactly the same; therefore, I don't feel comfortable concluding that the gray ones are only laser etched because the white ones are only laser etched. I don't want the white keycaps because I'm afraid they'll get dirty, plus I don't like the look of white on black.
So that's basically my predicament and I'm looking for any information that may be available. Also, I had initially wanted to make sure the keycap set would fit on my Filco. I'm pretty sure it will, but a second opinion couldn't hurt. With the link in my OP removed, nobody would know. But now you have a better idea of the product I'm interested in.
Also, note that I'm well aware of the numerous options I have when it comes to PBT keycaps. The answer I'm looking for isn't "just get a similar set from qtan/feng." I know I can pay $50-100 for PBT caps from another source, but the low price of this particular set is what caught my eye.
