## Questions & Answers

**Q: Are these flexible?**
A: Unfortunately, no they are not.

**Q: what  size it the set square?**
A: Its right there.

**Q: where is the hole to place on the vortex to measure the angle?**
A: SUSANLEE, 
THERE ISN'T ONE. 
ALSO, THIS SET AND I'VE HAD TWO REPLACEMENTS SINCE THE ORIGINAL PURCHASE ARE DEFECTIVE. I FOUND ALL MEASURMENTS ON EVERY PIECE ARE OFF BY A CONSIDERABLE AMOUNT. I MEASURED THEM AGAINST THREE DIFFERENT RULERS AND EVERY ONE WAS OFF. ADDITIONALLY, THE MEASURMENT MARKS ARE SO FAINT I CAN BARELY SEE THEM EVEN AGAINST BLEACH WHITE PAPER. DON'T WASTE YOUR MONEY.
