POLYMER47

Wudd you say?? It's our rubber!

Polymer47 is our proprietary rubber blend that creates our truly odor proof seal.  Now, we do use Food Grade silicone in a few of our products but Polymer47 is what is used in all our caps and sleeves that are part of the odor protection of our products. 

We have picked the proper blend of polymers (rubber) to eliminate "gas permeability" which is how odor is transported through rubbers like silicone.  Silicone rubber has 450 TIMES the gas permeability of our rubber blend.  Man, it's just science.  So if a competitor claims to be smell proof but is using Silicone in their designs we would find that claim very difficult to believe.  These products were custom designed and tested exhaustively to make sure we deliver the experience you are looking for. They are very durable and the grip of the rubber ensures it will not "slip" out of your pocket at the wrong time.  POLYMER47 also resists sticky things as well or better than silicone.

If you try us, you will like us...we promise.  If you don't we will give you your money back*.  No questions asked.  Always free shipping.  Always friendly service.  Got a question? let us know.
