Sonic Tools USA have created the newer NEXT toolbox line, which reinvents and improves upon their flagship designs. These toolboxes suit both entry-level and professional users, offering durability, style, and functionality through sleek design, high-quality materials, and innovative features that set them apart. Made from a single piece of folded steel, the drawers are super robust with increased weight capacity, especially in models like the S9, S12XD, and S15, making them ideal for serious users. These models feature excellent casters that roll quietly on various surfaces, reflecting Sonic’s focus on quality and user experience. The NEXT line also includes larger, heavier-duty casters, reinforced stainless steel tops, improved powder coating, stylish colors, sleeker bumpers, and new handle designs similar to the MSS+ line. If space is limited or you need a flexible rolling toolbox, the Sonic NEXT series, particularly the S9, S12XD, and S15, is a great choice.
