25 AWESOME MICROSCOPE SLIDES WITH GREAT VALUE – We hand-pick the most comprehensive 25 slides based on 20 years’ biology experience working with biological microscopy. These 25 slides cover four major fields of biology: (1) ALGAE and FUNGI.
DETAILED LEARNING GUIDE – Each slide represents a lesson of the “Beauty of Biology”. Our guidebook is professionally written, containing colorful pictures with detailed description of the anatomical structures, so you know what you are exactly looking at. Following our guidebooks, you will have the most fun and fantastic learning experience..
MAXIMUM QUALITY – Our slides are prepared by the professional laboratory with maximum quality. Each slide is polished to have rounded corners for convenience and safety. Slides are stored in a super durable plastic box. The plastic box is much safer for kids comparing to a wooden box which may have splinters that can thorn your fingers..

【CONDUCTIVE ELEMENT】- The oval-shaped conductive pad we use in the sole acts as a conductor of electron flow from the earth to your body. It makes our shoes genuinely grounding..
【WHAT IS GROUNDING】- The earth beneath your feet provides you with food and water. It also provides you with something very surprising - electrons. When you touch the ground with your bare feet or body, the electrons flow into you. This is called being “grounded.”.
【HEALTH BENEFITS】 - When connected to the Earth's natural electron current, many people experience positive health benefits like deeper, better quality sleep, less stress, more energy, improved circulation, reduced inflammation,etc.
【BAREFOOT SUBSTITUTES】- These Earthing shoes allow you to conveniently ground yourself when indoors or outdoors. They are "barefoot substitutes." It is not always convenient to ground outside during certain times of the year or for long periods of time..
【PERFECT DETAILS】- Ventilation ports add breathability and help shed water and debris. The shoes are easy to clean and quick to dry....
