Hair Extensions - Burmese Curly 4x4 Swiss Lace Closure - Natural Black (1B)

The Softest Mesh a Closure Comes In
Swiss sits at the delicate, pliable end of the closure meshes, so the open lane where you part reads like your own skin rather than a panel of fabric parked on your crown. It finishes the top where your wefts stop, and there's no strip of your own hair left out to comb and curl into the parting every wash.

Four Inches Each Way, One Part to Lay
This is the tightest base a closure is built on, four inches square, which means a single center line is really the only channel that has to sit down clean against your head. Less mesh to melt, less lace to fuss, and you still get to drop that part center, off to the side, or wherever the mood lands the day you sew it in.

A Spring the Bonnet Never Flattens
Burmese carries its own bounce, and the give in soft Swiss lets that bounce move at the part where a stiffer grade would pin it down. Sleep on it, wrap it, and the coil rises back on its own the next morning, because the pattern is grown into the strand and not something a rod set into it.

Two Finishes Off One Small Square
Because there's so little mesh here, a re-set only ever touches four inches, so you can flip the look as often as you want without disturbing a wide part. Wet it with a curl cream and the ringlets pull into deep, soaked-in definition; let it dry and break it up with your fingers and the same coil loosens into airy volume. The little Swiss patch stays flush to your scalp through the switch either way.

Sews Flush in a Few Short Rows
Made for a sewn install and a custom cap, it locks onto your braided tracks with a stitch dropped close enough to hold and no tighter. With only a four-inch square to seat, the seam settles in a couple of rows, and the pliable Swiss lands lighter on the cornrows than a firmer lace would, so the closure hugs the braids instead of tenting up off them.

Cuticle-Intact Hair That Takes a Mask
This is virgin hair with the outer scale layer still whole and lying flat, and hair like that drinks a deep conditioner in evenly rather than letting it bead up and roll off. Work a mask under the compact Swiss part the way our curly-care guide walks through, and the coil stays soft and fed from one wash clear to the next across a long install.

An Ounce at the Crown
At 28 grams it barely registers on the top of your head, no weight pulling on an install that already carries its own body from the curl. It's cut to sit with Burmese curly wefts, so the part and the length read as the same head of hair from crown to ends.

A Clean Rise to a Warm #27
Straight from the pack it's a true 1B, deep and neutral, and it'll carry a golden honey #27 that glows warm against that dark base without going brassy. Every bit of the hair's own dark pigment is still in there and no developer has ever touched it, so lightener climbs the strand at one steady pace with none of the streaky zones you fight when the color has been altered once already.
