It is a big block pillow, very flexible because of 6 square (19x19cm = 7,48 x 7,48") and 6 half blocks (19x9,5cm = 7,48 x 3,74"). All filled with felt, about 3 cm (1,18") heigh.
The advantage: you can work bigger laces and put the point you are working on always in an comfortable position. And: you can have it more flexible. We offer additional smaller blocks.
