Description

[EN]

When writing with chalk, whether on the blackboard or on the sidewalk-pitch, the whole chalk not only breaks but especially dirty hands. The whole chalk is inserted into this holder and by gradually tightening the bottom screw it is pulled out as required so that it does not break unnecessarily and at the same time does not get dirty. In addition, the chalk is much more comfortable to hold in this way. The holder is designed for classic school chalks of 12x12x100mm. In case you need more clamping force or thinner chalks, there is a groove at the end of the "pliers" for threading a suitable O-ring or hair elastic.

 

[CZ]

Při psaní křídou ať již na tabuli, či na chodník-hřiště se celá křída nejenom láme ale hlavně špiní ruce. Do tohoto držadla se vsune celá křída a postupným utahováním spodního šroubu se vysouvá dle potřeby tak aby zbytečně nedocházelo k jejímu lámání a zároveň nešpinila. Navíc se takto křída mnohem pohodlněji drží. Držák je určen na klasické školní křídy o rozměru 12x12x100mm. Pro případ potřeby větší síly upnutí, či tenčích kříd je konci „kleštin“ je drážka pro navléknutí vhodného O-kroužku nebo gumičky do vlasů.
