Our caps are made to fit specific jars, so that we guarantee physical compatibility between the caps and jars. Some caps are made in one piece from ABS or PP, others are combo or dual cap with an inner cap and an over-shell in same or different material. This is to give a mirror-like flat surface or a ground for further decoration. The caps are not just made to fit, but it looks good as one whole design. The caps can be customized by changing base colour, adding printing, lacquering and foil stamping.
