“I bought the smaller Pacto 360ml cup and the taller 500ml Calix cup, both are tested and fab, highly recommended. Kept my tea or coffee hot for ages, actually burnt my mouth a couple of times as thought there was no way it would still be that hot! Perfect for teachers, the cup has a lid so nice and safe, and it keeps that cuppa that you make in the morning hot until you get around to drinking it.
For thoroughness I also tested it with cold drinks and it kept my GnT nice and cold too.”
