Prym Flex frame – 120 mm With Pryms 120mm practical flex frame, homemade clutches, purses or makeup pouches can be enhanced. The flex frame is made of flexible, blue manganese and closes every bag by pressure in a highly reliable way. When open, it keeps the bag open and at the same time gives it an excellent stand. Working with it is simple because the flex frame is easily sewn into the tunnel. Instructions are included on the back of the package – so the fastening of a home-sewn bag becomes child’s play.
