The lens board has a stainless steel locking plate and spring-loaded screws to hold the Linhof lens board firmly in place. There is a velvet light seal to prevent any light leaks. The back is painted mat back to minimize the reflections. 

This lens board is 3d printed, there are some marks do to the 3d printing process. The material use is PET Copolymer, 3 time stronger than ABS. It's a high quality material made in Italy with excellent mechanical property and temperature resistance (see the specs in the pictures). With normal use it is going to last a lifetime.
