1. The suction cups feature only two leather flaps with magnets, which are very durable. They measure 7 x 7 cm in size and can be attached to clothing or placed in pockets at any time. They are suitable for most instrument cameras. 2. Made of black leather, it is safe and odorless. The suede side does not damage clothing. Take good care of the leather by wiping off dirt for longterm use. 3. The clip with an adjustable plate is the 'outside' part. Place the 'inside' part on the inner side of the clothing and the 'outside' part on the outer side. 4. The 45degree adjustable plate on the outer clip is flat by default. Press the screw points and rotate the plate simultaneously for a better viewing angle. Due to the strong magnets, be careful not to pinch your hands when using it. If the positions of the two clips are opposite, the force will weaken, causing them to fall off easily.
