Had no issues at all downloading or getting the zip file. Follow the setup / install instructions. Once you do that, you’ll have the Zip File. Zip files need to be extracted in order to use the files inside them (in this case the abr files for photoshop brushes). To do this, right click on the zip file. Choose Extract from the list, where you want the files extracted to, and left click ok. Very simple and straight forward.
It extracted just fine on my end. Once extracted the files should be moved to your Photoshop brushes location or wherever you access them if different… or within the other editing programs used (same with those, place where you normally access brushes).
Some editing programs need photoshop plugins in order to use the files. Some just need to be converted to png or another format. Check with your program for more information.
These brushes work perfectly and without any issues. Thank you for the offer!
