That Guy With Mastiffs Diamond Aluminum Keychain – Choose Your Design

Big Mastiff love. Pocket-sized attitude. 🐾😂 

Take your favorite That Guy With Mastiffs design wherever you go with this diamond-shaped aluminum keychain, personally sublimation-printed by Mastiff Mama Designs.

Perfect for keys, bags, everyday accessories, and Mastiff fans who want a little big-dog personality tagging along for the ride.

Because your Mastiff can't follow you absolutely everywhere. Apparently there are rules about bringing giant dogs into certain places. Rude, honestly.

🐾 IMPORTANT — Choose Your Mastiff Design

This keychain features a SINGLE-SIDED design only. Your selected Mastiff artwork is printed on the front, with the reverse side remaining undecorated.

Use the required “Choose Your Favorite Mastiff Design” dropdown to select the artwork you want.

YOU MUST SELECT A MASTIFF DESIGN FROM THE DROPDOWN OR YOU WILL NOT BE ABLE TO ADD THIS ITEM TO YOUR CART. THIS SELECTION IS REQUIRED.

Please double-check your selection before checkout. Your keys deserve your favorite Mastiff, not a surprise passenger! 😂

Pre-Order Information

After each pre-order period closes, I order the necessary blanks and supplies. Once everything arrives, I personally sublimation-print and assemble your keychain.
