This is a custom made mug leave your wording in the messages section exactly as you want it written. I only have upper case letters no numbers please . punctuation will be drawn on freehand. the capacity can fluctuate but is generally around 16oz.since this will be made for you from scratch, there will be a 1-2 week wait time. If you would like more than 40letters please message me and we can work something out. thank you, John
