WHEN IT'S MISSION CRITICAL, THE CASE MAKE THE MISSION POSSIBLE
Two friends meet in college in 1973 and start a business 4 years later - the rest is history. Now SKB Cases offers one of the most competitive ranges of vacuum, rotational and injection molded equipment containers available. In 2005, to demonstrate the quality of their products SKB began offering their Million Mile Lifetime Warranty on all hardshell cases.
SKB now offers more injection molded case sizes that any other manufacturer in the world. SKB is currently the only manufacturer to offer integrated TSA approved latches / locks on their iSeries injection molded cases, allowing airport screeners to easily unlock and relock the case for inspection, and preventing forced entry & damage. Servicing the entertainment, sports, military and industrial industries, it is no surprise that they are one of the top recognized brands in protective cases.
California Proposition 65
You may have heard that everything gives you cancer – if you live in California. The reason is that it is a California state law that requires businesses to provide reasonable warning about the use of any chemicals the state has decided could cause cancer, birth defects, or other reproductive harm. The list of chemicals and substances is extensive - currently totaling approximately 900.
For those consumers who live outside of California, you are not accustomed to seeing Prop 65 Warnings everywhere you go to shop, eat, buy groceries, fix your car, and are even posted at amusement parks.
SKB has been making cases since 1977. We have no reported cases of our products causing harm or danger to anyone. We believe in the safety of our products and we meet all the applicable safety requirements. We are unable to test against the 900+ chemicals listed for Prop 65 and to 100% certainty, and therefore, in an abundance of caution, we have placed the warning on our products to be in compliance with this California regulation. You will also see the Prop 65 warning on products that you buy outside of California, because we are unable to determine our products’ final retail destination.
For any questions you may have about our products and California Prop 65, please contact us at CaProp65@skbcases.com
