These are 100% genuine Aquabrite Acrylic pen blanks. The luminescent material creates super radiant and impressive pens. Normally these blanks would be 3/4 by 3/4, but the manufacturer was a bit off on the day the made these. They are 3/4 minimum on one face, but only a minimum of 11/16 one the other face. Some are actually greater than 3/4 x 3/4, but all are greater than 11/16 on both faces.
