Caffeine, a stimulant found in coffee, tea, soda, and energy drinks, is one of the most widely used drugs in the world. Its main use is to keep people from falling asleep, or to help them focus energy on a specific mental or physical task.
Our molecule models are ethically 3D-printed in Corvallis, OR, USA. As the world's oldest and highest-quality molecule model makers, we pride ourselves on using high-quality filament, well-paid labor, and making as little waste as possible. Satisfaction guaranteed or your money back, no questions asked, within 30 days of delivery!
All of our molecule models are made in three standardized scales: small (75,000,000:1), medium (125,000,000:1), and large (200,000,000:1). This means that any molecules you buy from us at the same scale will be accurate in size relative to each other and to reality.
