Number of Uses: Approximately 10 times I am selling this because my bird has grown and no longer needs to be weighed. It has been used only a few times and is in overall good condition. *To reduce shipping costs, the outer box will be folded for shipping. Thank you for your understanding. Product Features: ★ You can easily manage your bird's health by simply having it perch on the perch to measure its weight. ★ Weighs from a minimum of 0.1g to a maximum of 500g (displays in 0.1g increments) Please feel free to ask any questions in the comments. *CR2032 button battery x 1 (sold separately)
