It's a Triangle... shape the tip if it's is gray before the you chalk it again it is 100% triangle. If I am wrong I'll send you a triangle for real!!!!!!!
I would have to say its a Elk Masters tip, I never seen a blue Le Pro tip just brown looking ones.
When new, the tip had a gray hue to the fibers.
The reason I am asking is because I asked for an elk master tip to be put on, but it looks as though it might a be triangle. Just asking the experts at AZ.
