This 14-piece sticker set celebrates some of your most stellar endocrine and exocrine glands! Super silly illustrated versions of the thyroid, parathyroid, pituitary, hypothalamus, pineal, sebaceous, testicle, prostate, ovary, mammary, salivary gland, sweat gland, adrenals, and thymus. This might be the weirdest sticker set you ever own. Great way to share the magic of the body with friends or your kids. Even if you forgot what the thymus really does, our silly drawings will help jog your memory. And there's always Google, ya know. There's a Have You Got Guts? Sticker Set, too! These outdoor quality 3.25" square vinyl stickers were made in China, and come packed in cardboard and wax paper.
