A must-have for young scientists and wanna-be spies, this sleek little scope pretends to be a pen while it packs the double-duty power of an 8x telescope AND a precision 30x microscope. Slip it in your pocket and set off for undercover sleuthing, bird-watching, or microscopic investigation. Extend the telescoping barrel to view distant objects 8 times larger. Or slide it back to explore microscopic details on stamps, coins, insects—even skin—at 30 times the magnification.
