Students are always asking *Why?*. And sometimes that can wear on your nerves. Next time- just show them the cup! This cup has the appearance of a disposable cup but it is anything but that! This cup is blue in color and features the comical saying *I*m The Teacher...That*s Why!* on the face of the cup. Made of durable acrylic- this cup is double-walled to keep your favorite beverage cold without freezing your hand. The lid screws on so you don*t have to worry about spills in the car. The drinking straw is also made of acrylic and is specially designed to never fall inside the cup or be pulled out unless the lid is off. Since it is reusable you don*t have to deal with the hassle about throwing away cups everyday.****Features:*** Suitable For Cold Drinks*** Made of Durable Acrylic*** Screw On Lid*** Specially Designed Acrylic Straw*** Hand Wash Only*** Do Not Place In Microwave****Dimensions:*** Acrylic Cup - 6* x 3 3/4**** Acrylic Straw - 9*
