3.5x4 Dimensions Hit the Sweet Spot Between Coverage and Simplicity
Slightly narrower than a standard 4x4. Covers the part zone without excess lace to trim, fold, or manage. Fastest closure format to install while still accommodating center and moderate side parts.
Vietnamese Hair Lies Flat Without Heat Manipulation
Naturally fine strand diameter and tight cuticle compression produce a sleek, gravity-hugging fall straight from the package. No flat iron needed for the polished finish coarser closures require pressing to match.
Transparent Lace Works Across All Skin Tones
Colorless mesh absorbs whatever complexion it sits against. Reads as bare scalp without tinting, tea-staining, or concealer before first wear.
35-Gram Weight Prevents Detection by Touch
Light enough to sit flush without a perceptible bump at the attachment seam. Hand across the part zone reveals nothing but smooth, continuous hair.
Tight Vietnamese Cuticle Blocks Humidity
Compact cuticle layering seals the cortex against atmospheric moisture. Straight texture stays polished and frizz-free in conditions causing looser-cuticled origins to swell.
Liftable to 613 Without Structural Compromise
Virgin cortex with undamaged melanin processes cleanly through all ten lightening stages. Tight cuticle slows lift rate enough to prevent hot spots and banding.
Straight Texture Reveals Installation Quality
Straight strands lie flat rather than overlapping. Every aspect of the install, including adhesive line, plucking density, and lace edge, must be precise. Vietnamese hair rewards that precision with a mirror-smooth surface.

The 3.5x4 is a closure size that does not exist anywhere else in the product catalog. 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.
What 3.5 Inches Wide Means in Practice
For 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. The tradeoff is slightly less lateral range in exchange for a cleaner, faster install with less lace to manage. The comparison between HD and transparent lace types explains why transparent was chosen for this specific format, where durability under heavy Vietnamese strands takes priority over maximum invisibility.
Vietnamese Straight on Transparent Lace
This closure uses transparent lace rather than the Swiss lace found on the raw Vietnamese line. The transparent lace provides the durability needed for the heavier Vietnamese hair, and the straight texture exposes every detail of the parting line. Your install has to be precise, because the hair will show it. If this closure is part of a Vietnamese straight sew-in bundles or permanent installation, the 3.5-inch width means less lace surface to secure but also less room for adhesive error along the edges.
