Our dice have a core of fabric offcuts and thread ends from our soft furnishing business that are too small to be used for anything else and would otherwise end up in the bin.
The other layer of stuffing is a 100% hollowfibre fill. The core of fabric gives the dice a nice weight, while the fibre fill means the dice is still nice and soft to hug.
The fabric we use is an upholstery velvet, so it's very hardwearing and also has a treatment that helps repel liquids. So feel free to roll your dice across the floor!
