The Q-pid is made of of 6 tags with engraved equations. Our equation dog tags are machined from lightweight aluminum, given a lightly brushed surface, and then the equations are engraved into the surface. We are offering these as a complete set. The complete boxed set comes with all 6 tags, one 24" screen accurate stainless steel snake chain, the presentation box, and because the snake chain is notorious for pulling hairs we are now also including one 24" stainless steel rolo box chain. Each tag weighs only .5oz (15g) and they are made to be full scale at 60mm tall, 19mm wide, and 6mm deep. The complete set weighs only 3.5oz (100g) so you can wear all 6 without hurting your neck.

Please note that the screen accurate snake chain is notorious for catching/pulling hairs. The reason why we are offering this style chain is because it is the same style used in the video game. So in order to offer a screen accurate product we chose to include this chain. If you plan to wear these tags often then you might want to consider using the rolo box style chain.

The perfect finishing touch to your Sam Bridges costume. The Q-Pid is an integral part of the game and were used in the video game to link up different settlements to the Bridges/UCA chiral network.
