Stainless steel collapsible cup holds 2 fluid ounces. It measures 2" round and when collapsed is a little over 3/4" high. The cover is attached to a clip. I can engrave both the top and the bottom of the cup. Recommended fonts are shown in picture but more are available. I do have Greek letters and a few designs. Engraving is done on a diamond tip engraving machine in my smoke free home. I have over 19 years retail engraving experience. Please contact me with any questions.
