Jo Malone’s creative team once again wowed the market with a limited edition of four specialty fragrances, each bearing a customized zamac cap designed and produced by TNT Group. All feature a special antique-effect gold plating and assembled with a PP insert.

Zamak’s characteristic weight and cool touch enhanced the retro and luxury feel of these models. According to TNT Group, the main challenge was to achieve the special patina of the gold plating and ensure that that it had a consistent appearance over the four different caps. As each cap has its own geometry and features different colours and lights, great care had to be taken.

The production of each cap follows a meticulous multi-stage process, from die-casting to semi-automated and manual finishing operations.
