Abstract: Optical bodies are described. In particular, optical bodies having a birefringent multilayer optical film and a continuous adhesive layer with a thickness less than 20 micrometers are described. Optical bodies described herein exhibit reduced occurrence and severity of a non-uniformity defect known as “orange peel.

Abstract: A hair braiding device having a plurality of arms spaced in a tapered manner with the widest space at the arm's distal ends, the inner arms being of a substantially one piece V-shaped construction having connecting means at the distal ends and the outer arms having distal portions bent obliquely away from the outer arm linear shank portions which have perimeters which expand into parallel, oppositely disposed ear portions containing centrally disposed, aligned holes to be pivotally connected to inner arm apex holes with pins having coiled springs attached where the spring's free ends are secured by the outer surface of the inner arm apex and the inner surface of outer arm handles which are proximal extensions of the outer arm ear portions, so that pressure on the handles opens the arms to receive hair strands and release of the pressure causes the arms to close and clamp the hair strands so a hair braider is able to tighten a braided portion by pressing the hair braiding device against the braid and the hair
