This is a set of the following Switchbot products: ① Smart Lock Pro x 2, Retail Price: ¥17,980 ② Fingerprint Pad x 1, Retail Price: ¥8,784 ③ Rechargeable Battery x 2, Retail Price: ¥2,980 I am selling these because they were incompatible with my door. They have been opened, but are practically new as they were only tested for functionality. The double-sided tape on the main units has been removed because I planned to install them with neodymium magnets. Please use the spare double-sided tape included in the package for installation.
