I received several medium length boxes for my Arduino Pro Mini and ATTiny85 projects (see image). These boxes are beautifully made from good PTFE material. They have full length live loops and a strong long latch. Various protrusions and concavities are not noticeable, but they greatly contribute to the rigidity of the box. These special boxes are big enough to hold an Arduino Nano or ST Blue Pills (without the lid). However, this does not leave much room for a planar prismatic cell. I love these things though and will get more when I need them.
