It is a Vietnamese-specific dimension, slightly narrower than a standard 4x4 by half an inch. Vietnamese closure construction uses different cap templates than Brazilian or Malaysian production, so the 3.5x4 comes from its own production line. It is a distinct size, not a trimmed-down 4x4.\u003c\/p\u003e\n\u003ch2\u003eWhat 3.5 Inches Wide Means in Practice\u003c\/h2\u003e\n\u003cp\u003eFor dramatic side parts that push close to the edge of the closure, the 3.5-inch width restricts your options compared to a full 4x4.
