1. Look at the right flowers. Good bags are very neat for the flowers, and the butt joints are made closely and meticulously. Therefore, the cutting requirements for materials are very high, and there will be waste of needed materials, so the cost is high. Poor bags have no effect on flowers at all, or they are poorly made for flowers. 2. Good bags are molded at one time, with no extra needle holes, fine stitches and even wiring.
