Maureen Hong has brand new large optical trays in red, blue, and purple; 24 trays in each color. Dimensions: 12 3/8” x 7 1/4” x 2 1/4.” She paid $120 for each color but she's willing to sell them for $60 for each color. It just needs to be someone where she can drop them off or they pick them up since shipping will be too expensive. See the attached picture.
