Abstract: A wall mountable holder system may include a holder-mounting substrate having a plurality of mounting positions and at least one holder removably coupleable to the substrate. The holder may include a base portion, a plurality of protrusions extending rearwardly from the base portion, a first arm and a second arm extending outward from the base, a tab extending inward at a distal end of at least one of the arms, and at least one groove extending downwardly from an upper edge of at least one of the arms. Each tab may include a leading surface angled inward and rearward from proximate the distal end, and a trailing surface angled outward and rearward from the leading surface. An opening may be formed between the arms, proximate the distal ends, and the opening may be narrower than a spacing between the arms at each point between the base portion and the opening.
