Flame retardant grade 1 blackout satin fabric sold separately 150cm width 1m black [Fabric name Colette]

[Product Features] Cut and sold fabric with flame retardant, grade 1 light blocking, heat insulation, and heat retention effects. We will send you fabrics cut to lengths of 1, 2, and 3 meters. [Fabric Features] The fabric is a double satin structure with black thread woven into the structure. The front and back will have the same expression. You can feel safe with its class 1 light blocking (over 99.99%), heat insulation effect (56.4%), heat retention effect (33.8%), and flame retardant treatment (I-label). [Note] Although it is made of grade 1 blackout fabric, it is not completely transparent. In strong sunlight, a little light shines through and it becomes vaguely bright. Dark colors are more difficult to see through, so if you are concerned about this, please choose a dark color. The fabric is cut by hand, so the cut edges may be a little loose or the threads may fray. Thank you for your understanding in advance.
