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.

This gift was a hit

I got this mug for my partner who loves dinosaurs, particularly T-rexes. It’s perfect for her. I also got the shirt for her and some greeting cards for next year. It’s such a fun design and I love supporting a cool local artist/shop. This was my first time buying from here. I’m really happy with the quality of the mugs too.

T Rex mugs

What a perfect way to celebrate the season by sipping coffee from a T Rex Christmas mug! I can use this all year long. 'Dishwasher safe' is what sold me. Thanks guys!

I bought these for a white elephant gift exchange, and they were the hit of the party. Everyone wanted to take them home!

Love these mugs!

What is not to love about dinosaurs and Christmas together on a mug? I gave one to my brother and he loves it too!

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.
