Colorful jars have ladybug wings that open to invite little learners to investigate insects. Even children who normally shy away from bugs will be excited to capture and observe critters (and other items) in these engaging observation jars. Wings open to reveal a 3.5x magnifying lens. Screw-on cap and air vents keep specimens secure. Durable plastic jars measure 4½”H x 3½” in diameter. Grades PreK+ | Ages 3+
