Agrimark Ram Crayons are of the highest quality. Moulded into a honeycomb section tray, the block stays secure and does not break. Made using natural waxes, including beeswax, these crayons give a super quality mark with better durability whatever the weather. Even on wet fleeces, these blocks leave a good mark and the high level of pigment together with fibre included in the formulation means that these blocks leave a highly visible mark and need no rasping during use. Only fingertip pressure is required.
