The inside cup separated from the outside within a week

I got this cup because I wanted a new double walled cup (my old one broke). I like my water nice and icy cold. This cup fits all my needs! It still gets condensation on the outside a bit, but it doesn't sweat and leave a ring of moister on tables/surfaces. It keeps ice from melting well enough. I use this all the time for iced water at work and at home, and honestly, it's been a blessing. This cup keeps me hydrated!

This Slip N Slide Slipper is so good my mother stole it, to the point I only recently found it after 3 weeks of it being bought. So Fyi buy more than one so you can actually use it. As it's highly likely your parent, partner or sibling will steal it!
