Abstract
A marker with a replaceable nib. Refillable markers are well-known however, after the marker's tip, or nib, wears out the marker must be thrown away. The present invention solves this problem by providing nibs that can be replaced after being worn out. The replaceable nib includes a casing that at least partially surrounds the nib and allows for easy handling of the nib. The nib slides into an opening in the front of a marker body. The nib and marker body include complementary portions of a locking mechanism that allows the nib to be snap-locked into place when fully inserted. Nibs can be provided with different shaped tips to suit the needs of the user, and the marker body can include a nib spring that helps eject, or remove, old nibs from the body.
