I was looking for cheap double walled cups for my new Tassimo machine. Sometimes it takes a long time for me to finish the drink so I thought that thermal cups could keep my coffee hot that bit longer.
The cheapest I could find in the size of 330ml and more were around £15 for a pair and with rather mixed reviews. These Bodum glasses are only a little more, but you get the quality of Bodum. It is a lot of money for 2 cups, but then they are everywhere else for around £30 mark. I think Amazon is price matching House of Fraser sale price.
