I’ve promised Glow brushes for GIMP
There are 11 brushes in this pack.(??) Brushes are big, so if your GIMP cannot resize brushes, be sure to download yourself the latest GIMP version!

Those brushes are for GIMP application. They have .gbr extension and they won’t work with Photoshop. If you are looking for Photoshop brushes, just search within the Photoshop Brushes category.
