750ml / 26oz Reusable Plastic Tumbler with Straw and Lid - Reusable Smoothie Cup & Iced Coffee Cup BPA Free - (Red)

I've had two of these now - these are not well made, the straw initially came broken but i filed it off and continued using it. It smashed last night whilst being washed in the sink, on the bottom, like it were glass.

Great
