30 Brand New Premium Tyvek® RFID Secure Credit or ID Card Protector Sleeves

My Chase credit card recently expired and when I received a new one, I noticed that it had an RFID (radio frequency identification) chip embedded in it (your card sends out a signal and can be read by putting it near a reader instead of swiping it).  I did not feel safe with this information being transmitted and found these Tyvek RFID security sleeves that limit the transmission of this data.  This manufacturer sells these protective sleeves to the  Federal and State governments to use with the new U.S. Passport ID cards and enhanced drivers licenses.  These sleeves are made of Tyvek (which is an extremely durable, tear resistant and water resistant fiber) on the outside and has a special inner lining which blocks the transmission of the RFID signal.  NOTE:  The picture shows 8 sleeves but this is a listing for 30 sleeves. 
These are impossible to find in stores!

What Makes this a PREMIUM Tyvek Card and how is it different from other Tyvek Sleeves?
This Premium Tyvek sleeve is sturdier, will last longer and provide greater protection and security to your card.  It combines the magnetic strip protection of standard Tyvek sleeves with the extra protection of a special inner lining which blocks the transmission of your card's RFID signal.  My other Tyvek RFID Sleeves have Tyvek on the outside and the RFID foil lining on the inside.  I had these PREMIUM Tyvek RFID sleeves custom manufactured to have an extra layer of Tyvek on the inside so that the RFID lining will last longer and cannot rub against the magnetic strip.  With this extra interior Tyvek lining, the sleeves are thicker, sturdier and look better since you cannot see the foil lining.
