The HUNU cup is made from food grade silicone and bamboo. We work with a supplier who is FDA and LFGB certified meaning that materials meet the highest level of US and European standards. They are BPA free as well as free of a bunch of other chemicals which are commonly found in plastics.
The cup is actually 10oz if filled right to the rim so lots of space left over for extra milk or foam etc if you have an 8oz drink. Just be aware that if you fill it all the way to the very top it will likely spill a bit if you put the lid straight on so we don't recommend filling all 10oz!
