I purchased two 8oz cups, the magnetic Blue cup inner ceramic found scratched, exposing stainless steel material.
Really impressed with this cup. Keeps the coffee warm for hours, great lid that can be closed off to prevent spillage and, not that this will help anyone else, fits in either of our cars cup holders.
Its a good mug with ceramic inside..hot retention within 2 hours which for the size of 8oz it will be more than enough
I love my STTOKE Cup!! I have both the an 8oz. & 10oz. sttoke cup and I carry them whenever I travel!! Their design is so sleek that it always get the attention of others when I sip my coffee with it! Say no to take away cups & huge YES to STTOKE~ A shout out to Paige from Sttoke for your great customer service too! I highly recommend my friends to get sttoke-d!! Cheers~ ??
