Pure rubber latex squeegee for laminating. Most laminators feel happiest with 6" - some prefer 8" ! The 4" is used around fins, or for fine touch-up work.
Buy this whole length and cut it up if you wish - to the length that suits your hand. How useful is that?
Reusable time and time again - clean in acetone.
Need an 8" Squeegee? LS8
Or the normal 6" LS6
Smaller? LS4
