Assemble the lid
1. From the inner line, slightly fold in the 1st and 2nd lines. Then slightly fold out the 3rd line. Repeat on all sides.
2. Bend all corners.
3. Fold all sides covering the joints inside the 1st and 2nd line.
4. Lock in the flaps by bringing the bottom flap over the top flap.
Assemble the acrylic wall
1. Open up the wall sides and (pre)fold in all top sides.
2. Peel off the protective film (from both the inside and outside of the box).
3. Open it up again and lock in all 4 top corners.
4. Sit the paper lid on top of the wall sides to lock it into shape (it should fit snugly). To secure the top of the box to the base use ribbon or twine (there are slots at the base to keep the ribbon from moving).
