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. There is no limit to the engraving message. Fonts are shown in the last 2 photos in the listing. I do have Greek letters and a few designs.

FREE engraving is done on a diamond tip engraving machine in my smoke free home. I have over 20 years retail engraving experience. Please contact me with any questions.
