Wiseguy Hammer-on-buttons with embossed W monogram. Brass finish. Easy to use and quick to install; just push the 'nail' of the button through the fabric of your trousers and gently tap the bottom plate of the nail with a hammer to fix. Your pants are ready to go for Wiseguy's with loops. Great to order for creating more trousers 'loop proof'. This set comes with our 'spacing tool' for straight forward and easy application.
