A Note On Proper Folding (Applies to All Sizes)

注意事项1注意事项1

Points to Note 1

Proper Folding Sequence: Crease line 1 first, followed by line 2. This sequence is critical to ensure proper assembly of the box.

注意事项2注意事项2

Points to Note 2

Proper Side Panel Alignment When correctly folded, the side panel should have a slight convex shape with the outer edge sitting higher than the inner edge.

Troubleshooting: If the inner edge is higher than the outer edge, the box will not lock securely. To fix this, simply press firmly along fold line 2 to reshape the panel into the correct position.

注意事项3注意事项3

Points to Note 3

Final Shape Check: When the box is completely folded, a top-down view of the side should show a clean, rectangular frame.

Troubleshooting Tip: If the side appears as a straight “I” shape, the assembly is incorrect. In this case, please revisit and carefully follow Note 1 and 2.
