1. Precise Guidance The adhesive applicator features a positioning and guiding function, significantly improving adhesive efficiency. During application, a roller must be pressed on the underside to ensure the backing paper stays firmly in place. 2. Sharp Cutting The applicator for cutting textured paper performs zigzag cutting, making sharp cutting simple and effortless. The ergonomic handle design facilitates force application during operation, aligns with the guidance, and minimizes deviation. 3. Left and Right Differentiation Simple left and simple right—the two differ only when inserting vertical seams (inserting from to bottom: the single left tool inserts on the left side of the gap, the single right version inserts on the right side of the gap). The remaining 90% of locations have no functional distinction and can be used interchangeably. 4. Easy to Use The design is simple and compatible with various widths of textured paper. You can complete the task with just one pull and press. It's userfriendly.
