- Silky Vietnamese Body Wave Hair. 
- 1 bundle ±100 gram per piece
- Single Drawn
- Double Weft
- Steam Processed
 
Lengths 12" - 20 " only need three bundles for a full sew-in, while lengths 22" and longer need closer to four bundles to achieve a full, flowy, and glamorous look.
A few things to factor are the size of your head, the texture of bundles (for example, deep wave textures are fuller/thicker), if you're using a closure/frontal, and the desired finished style.
