ABSTRACT:
A bendable marker for use in areas where the marker is required to be flexible is provided with a base and a marker post which are joined together by a flexible sleeve. The flexible sleeve has a plurality of evenly spaced ribs which extend longitudinally along the sleeve from an upper end to a lower end. The ribs are evenly spaced apart with a groove being formed between each of the ribs. The ribs protrude from both the inner and outer surfaces of the flexible sleeve. If the marker post is struck, the flexible sleeve allows the marker post to bend relative to the base. The ribs strengthen and enhance the resiliency of the sleeve.
