A:AnswerThe product expands or pops up to 2 times for great holding or for propping your phone. At 2 pops it is just under an inch long. The top piece measures at 2 inches. You can move and replace it over and over and it doesn't lose any adhesive. It doesn't leave a mess at all. Best part is you can bend it down after you pop it open to use it as a stand.
