Well that's Christmas sorted!
I use Luxey all the time and decided it was time to introduce my sister. The starter pack was a perfect starting point (funny that!!) and was packaged beautifully while still being sustainable. As it was a gift, I haven't personally checked the functionality, however every single one of my personal cups has been flawless, so I can only imagine this pack was too, I added a marble sealed lid and my sister was rapt with the gift!
