We are taking over the industry by creating some of the most spectacular TCG accessories. GEM is located in the beautiful state of California where all competitive card games are in great popularity. Pokemon, Yu-Gi-Oh and Magic the Gathering are played by thousands of players all across our state.

Our small family ran business wanted to bring something new to the table, because simple rubber play mats and bland deck boxes just didn’t cut it for us. Our goal was to give what the players asked for; reinvent the most used TCG accessories. Our goal is to make the best TCG products you have ever played on. Elevate your game with GEM.

The Senjo cloth mat was GEM’s first breakthrough product, rivaling some of the big hitters in 2015. Not only did this product solidify GEM as a company, but also a competitor in its niche market. As GEM grew its brand, over the years, many of the upcoming products were still based around the original Senjo design layout.
