Prismatic Engineering Grade (PEG / EGP)

This is also a multi-layer sheeting, except that the reflective layer is made of microscopic cube-corner reflectors instead of glass bead sheeting can be distinguished by the pattern of small "squares" superimposed upon a hexagonal lattice grid. This sheeting is about seven times as bright as Type I. Cost is comparable to type III. Generally regarded to have a 5 year service - known as a "micro prismatic" layer.
