All Trackers are printed in the United States of America using PLA plastic which is biodegradable. They can be fully immersed in water and can withstand a wide range of environments but they will last longer if stored at a normal room temperature out of direct sunlight in a moderately humid room. The plastic will degrade faster if left in a place with lots of microorganisms so you may want to periodically swish it in a bath of warm soapy water. If for some reason you were to bury your Tracker in the dirt it should last about 6 months before showing outward signs of decay. If left in the sun the colors will fade over time as with any plastic. We have tried to make the design as durable as possible but since Trackers have only been around for a month or so it is still unknown how well they will hold up over time with normal use however, PLA plastic, when cared for properly, can last up to 15 years without breaking.
