The chalk holder consists of a spherical container made of translucent, ice coloured polyethylene, with a diameter of 400 mm. Due to its innovative design it protects chalk from air currents.
The clover-shaped base, made of aluminium, provides sufficient weight to ensure the stability of the whole structure. It is equipped with 60 mm diameter wheels. The wheels only act when the structure is inclined, ensuring stability during use and allowing for mobility.
All metal elements such as bolts, shafts, etc. are zinc-coated.
After a degreasing treatment, consisting of a pressured phosphate bath, the structure is painted with polyester powder paint and polymerized at 200° C in an oven.
