Rattan cane webbing is a handcrafted product. The artisans select the straight and soft rattan cane to weave into the webbing. While weaving, the artisans have to calibrate the net meticulously to make each pattern uniform in the net. Therefore, it takes more than 10 days for one artisan to knit a long rattan webbing sheet with the dimension: 45 centimeters wide and 15 meters long. The final product is beautiful and durable to the time. Moreover, this product is easy to clean and maintenance.
Product name: Rattan webbing.
Usage: For rattan furniture.
Dimension: Width 45cm, 60cm, 70cm, 90cm,... X 15m length.
