The Urban Dictionary Mug
It arrived three weeks after ordering but given the holiday rush and inability of shipping to keep on schedule arrived late but was perfect little gift from me to my wife for her morning coffee with her "nickname" on the mug.
I liked the photo on your website and so I ordered the mug. You sent it right away, and it looks great!
Arrived carefully packaged
me and the boys when i get vodka mug
I ordered 3 of your mugs, with different names on them. There was a typo in the information about the name on the back of each of the mugs. This wasn’t a dealbreaker because the people who received them liked them. However, it would be nice if somebody who has basic proficiency in spelling English words could proofread the script for all of your names before they’re prepared.
Arrived on time. Great packaging. Communication with vendor was top-notch. High quality item.
I love it! Thanks! So
Great present for a retiring colleague with custom saying she's known for!
Loved this mug! So unique and you can edit the text to add something unique.
I gave it to my friend who took money from me and never returned.
I love the fact that I was able to customize my name since I've never been able to find anything with my name. The only downside is it's smaller than I thought it would be (I guess I didn't pay much attention to that), wish it was bigger, only about 10 oz total.
It's simply awesome; and plus, the word means a lot.
Really fast and looks great! Took a chance on Christmas gift and it was a success!
Awesome mug feels really nice good weight and color although I think the shade could be a little brighter when it comes to the highlighter yellow, I am still pleased with the outcome and the fact that a whole passage was so neatly printed onto the product, very pleased with the packaging too! That made it so easy to wrap just in time for Christmas. Who knew!!
okay so the mug was mid but when you have a genz meme and give it to one of the most serious people you know then it's pretty funny
Nice mug, great feel‼️
Perfect!
Good quality ceramic cup! Worth the novelty price!
Perfect gift for my gf
Looks great! Came quick
