In collaboration with Lexus, and in celebration of the LS600h Hybrid, Visionaire No. 51 is environmentally sensitive. The puzzles are made from partially recycled paper, non-toxic inks and chlorine free materials. They were fabricated at environmentally sustainable factories that recycle all byproducts, including heat generated during production. Each set of six puzzles comes packaged in a slick, 8x8-inch embossed cube. Available in black or silver.
