The set contains :
6 cables of 95 cm, 6 cables of 50 cm, 3 flexible cables of 95 cm, 20 T-pins, 1 tape measure (inch and cm), instructions
A professional accessory to block your works. You pass the cables through the edges of your work, then you pin the cables by stretching them outwards to flatten the work. The great advantage is that the work is not stretched at the level of the pins, but that the tension is distributed over the entire edge.
