Rapha x Frank Green - Reusable Cups

Rapha has collaborated with Frank Green to create a run of very smart looking Reusable cups.
Very tempted by one of these but I own way to much Rapha gear already and this could tip me over the edge into becoming a brand fanboy.
There're available exclusively in Rapha's Clubhouses. They feature a double walled construction to keep hot or cold drinks insulated, whilst remaining BPA free.
Each purchase includes a free coffee and any coffee ordered in a reusable cup will receive a 25p discount.
