Koopman Screwdriver Set 13pcs

Koopman Screwdriver Set 13pcs is a multifunctional screwdriver set with 12 bits stored inside the handle. The set contains 13 pieces in total, covering common DIY fastening tasks. Bits are held in the handle for compact storage and quick access. The design keeps the tool small enough for household repairs, furniture assembly, and general maintenance. The handle integrates bit storage rather than requiring a separate case. No additional materials, drive sizes, or torque ratings are specified beyond the 13-piece count and 12 stored bits.
