Masu box with lid origami tutorial (Traditional)

Easy Origami Masu box with lid.
Paper size: Two 15cm x 15 cm
Finished box size dimension is: 5.5cm x 5.5m x 3cm
For the lid, be sure not to fold all the way to the centre so the lid is slightly bigger. Please watch at 6:00 https://youtu.be/-cCLXlYt7-Y?t=359
This is a arrangement of traditional fold. I modified the folds to make a shallow lid.
