The Truweigh Shine Scale stands out from the crowd on any shelf! This luxurious rainbow scale fits nicely in a pocket or bag, but the small size does not sacrifice function. This scale can accurately weigh up to 100 grams. It can easily switch between g, kg, lb, oz, and lb:oz. The readability is 0.01g, which is ideal when weighing flower. This makes it easy to stay consistent with packaging or personal dosages. Even the weighing platform has that gorgeous rainbow finish. This scale can be quickly and easily calibrated, and calibrating is highly recommended before the first use. This ensures that the readings will be as accurate as possible. A few things to avoid when using the Shine are unlevel surfaces, radio frequencies, high humidity, wind or air currents, vibrations, and extreme temperatures. These conditions can negatively impact readings. Each mini scale includes 2 AA batteries and a limited 10-year warranty.
