HoloShow is reuseable many times over and can be removed and re-rigged in different locations. However the real silver in the net does tarnish over time when it is exposed to air, and over a period of several months it will go brown if it is used a lot or incorrectly stored. This time period will vary with the amount of exposure to light and air, and other environmentals such as humidity and temperature.
To extend the life of HoloShow, we recommend that you store it in an airtight, lightproof bag, squeezing out the excess air before storage.
