Limited edition. The material used for the holographic effect is unusual. It is not a vinyl transfer, and it feels like plastisol ink once set. The process uses a transparent sheet of compressed dust particles, melted onto the water based adhesive after curing through the conveyor. It feels soft and flexible and does not feel heavy when worn. If you own any of the mantles, the ink feels very similar in weight and flex. This is an experimental shirt, produced in a very limited edition run. A holographic collector card is included, individually hand cut and set in a hard plastic graded protector case, with every order.
