Jawbreaker R2

Our Group Buy for this product is over now :( But we will come back with more fun designs in the future! If you want a custom commission, feel free to message us with your requests!


The Mason60 is cast from a gypsum resin composite. Once the case is demolded and then sanded, it almost feels like marble- cold and smooth. It's heavy, impact resistant and sounds great!

There may be some small air bubbles on the surface due to the casting process. Due to the hand made nature of this product, no two pieces will be identical in terms of pattern. This product is sanded by hand and so the external dimensions and contours may vary slightly. It will never be as accurate as a CNC'd product, but that is part of the charm of something literally sculpted by hand!

Colors will be close to what you see in the photos (as far as one can tell from a phone or monitor).


The Mason60 is sealed with beeswax and is water resistant, but please wipe off any moisture straight away to avoid leaving a mark on the wax coating. Please also keep your Cheetos away! Clean with a damp cloth and if needed you can reapply some wax (you can use Vaseline), though this shouldn't be needed for a long while.

While strong and impact resistant, it will shatter if you drop it from a height onto a hard surface. It will scratch if impacted with something sharp, but minor scratches can be sanded out.


We are a product design studio based in Hong Kong, specializing in creating beautiful cast objects! We are currently focused on keyboards and also offer a line of coffee accessories (pretty sure there is a sizable overlap between these interests!). As we make everything inhouse, we have more direct control over quality and timeliness vs outsourcing the manufacturing.
