Christmas mugs

I bought the "Things could be worse" Christmas mug last Christmas-love it-and now have the new Prehistoric one. Love it too! They are sturdy and prehistorically beautiful!

Adorable agents of destruction

I love everything about these mugs. They’re hilariously awesome.

Couldn't Wait!

You can't contain a T-rex let alone 4 per mug! They're already out and in use. Great size and love the knitted look.

T Rex Holiday Mugs

Purchased as a gift for a Dinosaur enthusiast. He's also a comedian, musician, and historian. He LOVES them! Great quality mugs and printing. TY

Perfect Christmas mugs

The quality is amazing as usual. My husband asked who helped the t-rexes put the star on the tree. He thinks it was a brontosaurus that became Christmas dinner.

Prehistoric Mugs

Purchased one for my son and one for my daughter's boyfriend; both who are hard to shop for. The mugs shipped quickly and were packaged well. Both guys thought they were funny and said, "That had to be one big Christmas tree." LOL.

Dinos @ xmas!

Sent as a gift to a dear friend. She was delighted! Delivered just in time. She had purchased some gourmet cocoa! Perfect.

Love them!

My mugs arrived just in time on Christmas Eve! We love them and I plan to use them all year long. I also bought the Christmas cards this season and they were so much fun! Love your stuff!!


I love these mugs! Actually I love and own all the Calamityware mugs (except the red things could be worse mugs, don’t like the red). Great size, great quality, everyone loves them

Great mug (could have been larger, but you can't have everything)

I do prefer a larger mug, but you can't have everything, right? I bought the T-shirts with this design for everyone in my family (3 sons, 1 daughter-in-law, 1 girlfriend, 1 husband) but couldn't buy one for myself because of size issues. *sigh* But I bought myself a couple of these mugs so I'd have something with this cute design on it. The mugs are very nice, straight-sided rather than curved, and just right for a cup of tea. (Even if, as I say, I'd have been even happier if they'd been larger.) I do so love the design. All the stars.
