Hagrid then took them shopping for their school supplies. Textbooks, quills, parchment, ink, uniforms. Their last shop was Ollivander's, a wand shop.  It took three tries, and a broken vase, for Harry to get the correct wand, an 11 inch holly wood wand with a phoenix feather core. One of two to ever be made. Solis got his on the second try, a near 12 inch cedar wood wand with the core of a dragon's heartstring.
