Ysivonu 12A Brazilian Remy Human Hair Bundles 4-Pack Natural Black 18-24in Glossy Straight, Double-Wefted

Ysivonu 12A straight Brazilian Remy virgin hair bundles—four 100% unprocessed bundles give a full, glossy sew-in or quick weave that can be cut, colored, and styled like natural hair.

These Ysivonu bundles are raw, unprocessed Brazilian Remy hair with one-direction cuticles intact, sold in a recommended set of four bundles weighing about 400g total. Offered in natural black and available in multiple lengths, the hair arrives with double machine wefts for minimal shedding and a smooth, consistent texture. The product suits sew-ins, wigs, and quick weaves and is intended for styling flexibility while maintaining a healthy look.

How durable and reusable are these bundles?

The 12A grade Brazilian Remy hair in this set is cut in one direction and kept unprocessed, which helps preserve strength and reduce tangling. With proper care—sulfate-free shampoo, conditioner, and gentle heat styling—each bundle can be reused multiple times.

• Double machine wefting for secure seams and reduced shedding
• One-direction cuticle alignment minimizes matting and tangles
• No chemical treatments, allowing safer coloring and restyling
• Approx. 400g total weight provides fuller density for repeated installs

Can I color, curl, or straighten these bundles?

Yes—because the hair is raw, unprocessed Remy, it accepts chemical and thermal styling similarly to natural hair. Avoid excessive heat and use professional-grade color products for best outcomes; strand testing is recommended before full-color application.

• Safe to bleach, dye, perm, or highlight with care
• Holds curls and straightening treatments when heat-protected
• Will blend seamlessly with your natural hair when matched correctly
• Recommend strand test to determine timing and developer strength

How many bundles do I need and what lengths suit different looks?

This listing includes four bundles, which typically create a full, voluminous sew-in or wig for most head sizes. Length choice affects weight and movement—shorter lengths are lighter and easier to manage, while longer lengths deliver dramatic flow and require more maintenance.

• 4 bundles (about 400g) recommended for a full install or wig
• 18–22 inches for shoulder-to-midback styles with good bounce
• 24+ inches for long, flowing looks—expect more tangling risk without regular care
• Shorter sets (12–16 inches) offer easy styling and less daily upkeep

What makes Ysivonu Remy hair different from synthetic or non-Remy hair?

Ysivonu's Remy designation means cuticles are aligned in the same direction, helping the hair remain soft and tangle-resistant. Because the bundles are unprocessed and sourced as raw Brazilian virgin hair, they maintain natural sheen and texture that synthetic fibers cannot replicate.

• Natural cuticle alignment preserves softness and realistic movement
• No animal hair, lice, or chemical odor—clean and ready for styling
• Minimal shedding due to tight, neat double weft construction
• Feels and behaves like natural hair when washed and styled correctly

Who is this for: These Ysivonu 12A Brazilian Remy straight bundles are ideal for anyone seeking high-density, versatile human hair for sew-ins, quick weaves, or custom wigs—especially users who want unprocessed hair that accepts coloring and heat styling. Choose this set if you prefer a natural black base that blends easily, need four bundles for a full look, and value longevity through proper maintenance.
