strafe rgb Silent RGB Key Cap Replacement Order Help!

Hello can anyone from Corsair help me, I just bought the Silent MX Strafe RGB a few weeks ago and am loving it. Although I had to replace the keyboard 3 times due to cracks and some keys malfunctioning, I think I got the perfect copy this time. My favorite feature of the keyboard are the curved key caps that come with it, WASD QWERF, etc. but I am looking to get a set for 1-2-3-4-5. I saw only the K70 had these and was interested in purchasing the set on your website for $15, but I saw there was a replacement set for the K60 for $9.99. There is no description or information for this, will these keys fit on my Strafe and do these include the ENTIRE keyboard set of 37+ keycaps?

Also, is there a way I can custom order the 1-2-3-4-5? I do not want to order the $15 pack because I don't need the WASD, wrist rest, and key puller since the Strafe already comes with all these. I am just looking to get a custom set of 12345 caps since I do like the feel of these rubber gripped keys. Thank you and please give me a solution thank you :)

P.S- What is the best way to clean this keyboard? I don't want to pull out all the keys unless it gets really filthy but I imagine dust particles will get inside and under the key caps. Do I just use an air duster?

The K60 keycaps should work but they will not allow light to pass through the keys while the K70 keycaps do.

You can use compressed air or a soft brush to remove dust from the keyboard.
