Gillette Venus Extra Smooth Womens Razor Blade Refills, 6 ct

6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number.

A blade is the sharp, cutting portion of a tool, weapon, or machine, specifically designed to puncture, chop, slice, or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are intended to cut. This includes early examples made from flaked stones like flint or obsidian, evolving through the ages into metal forms like copper, bronze, and iron, and culminating in modern versions made from steel or ceramics. Serving as one of humanity's oldest tools, blades continue to have wide-ranging applications, including in combat, cooking, and various other everyday and specialized tasks.

Blades function by concentrating force at the cutting edge. Design variations, such as serrated edges found on bread knives and saws, serve to enhance this force concentration, adapting blades for specific functions and materials. Blades thus hold a significant place both historically and in contemporary society, reflecting an evolution in material technology and utility.

Gillette is an American brand of safety razors and other personal care products including shaving supplies, owned by the multi-national corporation Procter & Gamble (P&G). Based in Boston, Massachusetts, United States, it was owned by The Gillette Company, a supplier of products under various brands until that company merged into P&G in 2005. The Gillette Company was founded by King C. Gillette in 1901 as a safety razor manufacturer.

Under the leadership of Colman M. Mockler Jr. as CEO from 1975 to 1991, the company was the target of multiple takeover attempts from Ronald Perelman and Coniston Partners. In January 2005, Procter & Gamble announced plans to merge with the Gillette Company.

The Gillette Company's assets were incorporated into a P&G unit known internally as "Global Gillette". In July 2007, Global Gillette was dissolved and incorporated into Procter & Gamble's other two main divisions, Procter & Gamble Beauty and Procter & Gamble Household Care. Gillette's brands and products were divided between the two accordingly. The Gillette R&D center in Boston, Massachusetts, and the Gillette South Boston Manufacturing Center (known as "Gillette World Shaving Headquarters"), still exist as functional working locations under the Procter & Gamble-owned Gillette brand name. Gillette's subsidiaries Braun and Oral-B, among others, have also been retained by P&G.

A razor is a bladed tool primarily used in the removal of body hair through the act of shaving. Kinds of razors include straight razors, safety razors, disposable razors, and electric razors.

While the razor has been in existence since before the Bronze Age (the oldest razor-like object has been dated to 18,000 BC), the most common types of razors currently used are the safety razor and the electric razor.

Venus is the second planet from the Sun. It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth. Venus has by far the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover. At the surface it has a mean temperature of 737 K (464 °C; 867 °F) and a pressure 92 times that of Earth's at sea level. These extreme conditions compress carbon dioxide into a supercritical state at Venus's surface.

Internally, Venus has a core, mantle, and crust. Venus lacks an internal dynamo, and its weakly induced magnetosphere is caused by atmospheric interactions with the solar wind. Internal heat escapes through active volcanism, resulting in resurfacing instead of plate tectonics. Venus is one of two planets in the Solar System, the other being Mercury, that have no moons. Conditions perhaps favourable for life on Venus have been identified at its cloud layers. Venus may have had liquid surface water early in its history with a habitable environment, before a runaway greenhouse effect evaporated any water and turned Venus into its present state.

The rotation of Venus has been slowed and turned against its orbital direction (retrograde) by the currents and drag of its atmosphere. It takes 224.7 Earth days for Venus to complete an orbit around the Sun, and a Venusian solar year is just under two Venusian days long. The orbits of Venus and Earth are the closest between any two Solar System planets, approaching each other in synodic periods of 1.6 years. Venus is the easiest destination to reach from Earth because of the low delta-v needed, and is a useful gravity assist waypoint for interplanetary flights from Earth.

Venus figures prominently in human culture and in the history of astronomy. Orbiting inferiorly (inside of Earth's orbit), it always appears within 47° of the Sun in our sky, as either a "morning star" or an "evening star". While Mercury also stays near the sun, Venus appears more prominent, since it is the third brightest object in Earth's sky after the Moon and the Sun. In 1961, Venus became the target of the first interplanetary flight, Venera 1, but radio contact was lost before it arrived in May 1961. The first successful flyby was by NASA's Mariner 2 craft in 1962. This was followed by many essential interplanetary firsts, such as the first soft landing on another planet by Venera 7 in 1970. These probes demonstrated the extreme surface conditions, an insight that has informed predictions about global warming on Earth. This finding ended the theories and then-popular science fiction notion about Venus being a habitable or inhabited planet (see Venus in fiction).
