This is a used 4 line phone system from my business. Specifically, it is a Panasonic KX-TG4000B base station / answering machine and one KX-TGA400B handset. The handset case is worn, but the guts were all replaced a few years ago. Both units work perfect and the battery is good in the handset. This is a very budget way to have a 4 line phone system. Included is the power supplies, charging cradle, and owners manuals. Shipping to be a flat $20 to the lower 48.
