Quarter-square units:

• Unique Non-Slip Coating
• This ruler features an exact measurement around the perimeter – no more accidental cuts and squaring your blocks has never been easier
• Unique Non-Slip Coating - Can be scratched off by contact with an abrasive surface, rubbing against other rulers/tools or coming into contact with oils/lotions on our hands. The adhesive wearing away from the edge of the ruler will not effect its grip as the “hold” is in the majority of the ruler. The numbers and lines will not be affected from the wearing off of the adhesive.
