2X Shutter Button Aperture Dial Wheel

This replacement unit measures approximately 25 mm in diameter and weighs 8 g per piece. It is constructed from durable black plastic and includes exactly two shutter button aperture wheel turntable dial units per package — no additional accessories or tools are included.
