Swing flags are typically made out of 8mm China Silk (except for the "Large & Light" which are 5mm making them more delicate - more info here) and come in 2 sizes: regular (upper left) and large (upper right). They come with an organza bag to store them in. The video below compares the two sizes side-by-side; regular on the left and large on the right.
Swing flags work by simply holding the actual fabric in the middle on the longer side and allowing the weighted "lead corner" pull the silk along as you move. How gently you treat them will determine how quickly they wear. Find out more about swing flags and how they work.
Please note: although the weight is distributed, this item still should be used with care. Dyed4you is not responsible in the event of an accident while using a swing flag. Use at your own risk.
