Texture tips for sculpting

These are like those expensive greenstuff or clay sculpting tools that I saw a guy charging $50 for, but they're free!
These are all Texture Rollers found on Thingiverse that I used a Blender Lattice modifier to quickly blow out into a Q-tip shape. The hole in the centers is 4.4mm wide, to accomadate the acrylic rods I happen to have lying around.
