Non-Modular Pentagons: 66

All the boxes shown here were designed by Tomoko Fuse, with some modifications of my own. Each lid required 1 sheet of paper; each base required 1 sheet.
 
Tomoko specifies A4 size paper (210 mm by 297 mm) , but her instructions allow for significant adjustments to the sheet size. I have been able to vary the dimensions even more than what is shown in her book, producing boxes of many different sizes.
 
These beautiful pentagons are so challenging! They require many precise pre-creases and a tricky "twist down" technique. Try non-mod squares first before attempting these.
