The Shell is a mono-material casing, made from only aluminium. Unlike many other deodorant stick packaging it contains no plastic.

To create a usable case that had a pushing action for ease of use, we went back to basics. Instead of having an overly complex twisting internal system (which is only possible if made out of plastic) we looked at how our hands could be the pushing force.

With the intent of making the case last for as long as possible, and infinitely recyclable if needed, we knew the case had to be made of aluminium.

Perhaps one of the most recyclable materials on earth, aluminium not only provided us with a long lasting product, but one that could be recycled at the end of its life back into another aluminium product of the same quality.

Unlike plastics that if recyclable are degraded in the recycling process (Ie. plastic bottles often get turned into packaging). Over 75% of all aluminium ever produced is still in use due to its perpetual recycling attributes, unlike plastics where only 9% has ever been recycled (Alumeco, 2021).

For the colouring of the cases, we decided on the same process that is used to protect satellites from their harsh outer space environments, anodising.

For the simple reason that it stabilises and seals the aluminium, increasing its lifespan, thus allowing the case to be used for longer as well as being the most environmentally conscious choice.

Anodising, unlike almost all metal treatments, produces no hazardous waste, is water based, and uses no VOC’s (volatile organic compounds)(Greenspec, 2021).

Powder coating the cases was the alternative option, though by comparison to anodising, powder coating reduces the recyclability of the aluminium and is also prone to chipping, ultimately reducing the lifespan of the product.

Luckily, we’re also huge fans of the aesthetic qualities of the anodising process as well!
