EASTER HOURS: Freight services do not work on statutory holidays so deliveries will not be made on statutory holidays. We will not be despatching orders containing yeast on days which will result in the yeast sitting on the network over the long weekend. We will be responding to email support over the break. Thanks!

Internal diameter 7.9mm, gauge 13.6mm, external diameter (within the "groove" 12.7mm (ie it fits a 12.7mm hole).
