Hello @star and welcome to the forum!
The both download links take you to ko-fi. On ko-fi you have to enter the amount you are willing to pay into the input-box on the right side (that is the box where a pale 0 is in), that can be anything even 0, so you can get these brushes for free if you want. After you have entered your amount, let’s say 0 into the box, you have to click on the blue bar below saying “Get Now”, on the opening page you have to enter your email-address and your name and click on the blue bar below, on which is written “Checkout Now”, then you’ll be presented another site where you have to scroll down and click on the black bar “View Content”, that will present you a dialog with two download buttons, one for the description and the next for the bundle. It is a good idea to download both.
Now you have downloaded them.
If you have issues to download them from China, then please send me a PM. To do so, just click on my username or on my avatar and then on the blue button named “Message”.

By the way, your English is very good. But should you search for a good translator, then try DeepL.com, it is currently the best available translator.
