These are Hand Crafted Copper Funnels. I made one for a customer and thought I would make a couple more. They are list on eBay as well as here. The 10cm one has a cone diameter of 10cm hence the name the cone depth is 10.5cm and the spout 8cm long. The 13cm one has a 13cm cone diameter and a depth of 11cm and the spout is 12cm in length.
If you would like a copper Funnel of a specific size please contact me and we will see if we do business.
