Kid size view finders come with lifelike photos are are easy for little ones to use. Slide in a disk, then pull the lever to switch from one picture to the next, then change disks to see even more insects, spiders, birds, animals, or the sun, moon, and planets. Viewers measure 4 1/2" each. These items are in nice condition but are not brand new so they may show some signs of wear from previous use. Please see pictures for details. Thank you.
