Hexagon's side is 4 cm, the thickness is 1 mm.
It is possible to make cards boards of the same size, but for 8 holes (specify when ordering if you need these).
Material: ABS plastic.
Flexible, optimal size, comfortable in the hand, the marker writes well on them (it is convenient to mark the numbering and make other designations).
A detailed diagram of their refilling will be included.
The price set is per piece.
I recommend ordering tablets of several colors - it is more convenient to weave complex patterns.
Plastic colors available for printing are shown on the picture.
I also recommend a set of additional weaving tools (clips, pins, shuttles):
