These European styled glazing pins are super slim and very easy to use. Each rod has 18 glazing pins.
 
The recommended process of use is to gently bend the first pin at a 90º angle, position it in the desired location on the sash, while holding onto the rod with one hand, tap into place with the European Glazing Hammer and twist to snap cleanly free. 
 
The real beauty of these pins are that they are easy to bend out of the way and simple to avoid running into when applying the linseed oil glazing putty with a putty knife.
