Jekca - French Bulldog - Small (03S-M03) Challenging the conventional way of building bricks, JEKCA aims at creating sturdy and detailed models that can fit to everyone's daily life. With JEKCA's unique Brick-through Interlocking System, you have the option of making your creations a bit more permanent. Depending on your dedication, fortitude and level of addiction to various streaming services, these puzzles will take maybe a day, two, or even a week, but the result of having a new blocky pet is well worth it. Each kit has their own detailed how-to build guide!
