1What kind of material is this "super clear epoxy"??
It's a "Crystal Resin Neo" made by Nissin Resin in Japan. The point of this resin is, "super tolerance for turning yellow". It seems, general epoxy resin turns into yellow after a certain period time but this resin has a tolerance for it (keeping it crystal clear). Similar items (I am not sure their quality but) also can be found in Amazon and we can try as we wish!
