Not all stainless steel is created equal. 
Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all the standard 440-series stainless alloys with high carbon content. As expected, it is also the most expensive of the 440 series alloys and requires multiple rounds of heat treatment and cryogenic treatment to achieve its superior mechanical properties. Though stainless steel has 20% less load capacity and is slightly softer than our standard 52100 chromium steel used in most of our bearings, stainless steel is an excellent alternative for use in wet conditions, if you wash your bike often, or where sweat can be a problem. Enduro Bearings also uses LLB type seals and CRC Marine grease in these bearings to additionally water proof against the elements.  All Enduro stainless headset bearings carry a limited lifetime warranty.

The Enduro line of headset bearings consists of two basic performance levels that are a substantial step up from standard bike industry specifications. Enduro "entry-level" headset bearings feature premium materials like Black-Oxide treated races and carry a two year warranty, while our premium 440C stainless headset bearings carry a full lifetime warranty. 

All Enduro bearings are always engineered with the largest balls possible and feature dual lip labyrinth seals for maximum protection against sweat and the elements and to contain the 90% high pressure water proof grease, keeping everything running smoothly for the duration. The Angular Contact (A/C) design of Enduro headset bearings allow all balls in the bearing to engage the load, spreading the force over a larger surface area minimizing any possibility of premature wear and greatly extending bearing life.

Keeps the bees and bugs out of beverages
Great . I have used on several different brands of drinks and they work nice to cover your drink once opened. They don’t prevent the spills but reduce the spill !! And the slide into your shirt or jeans pocket great!

They is a soap for every need in here, whether you need a soap to brighten dark marks or a soap with a great scent or hydrating, this pack has it. My skin feels good, not too dry but at the same time not too greasy or that feeling of residual stuff. Overall great quality soaps.
