REVO blank plano lenses. The sale is only for the blank plano crystal lenses as it is. The lens measure 69 mm in diameter.
Please be aware that edging the lenses may compromise the REVO finish coating due to the harsh chemical used to temper the lenses. I make no guarantees outside the shape and form as listed here.
