What frequencies do they block?

Hi Don, Thank you kindly for your question. Please note our RFID Blocking Sleeves protect 100% fully against high frequency radio signals operating at 13.56MHz, which credit cards and passport smart chips operate at. Please note they are not designed to operate for low frequency signals such as 125KHZ, which are typically used for office workplace & key cards (older cards). Happy safe travelling this summer - Robin Wright of Alpine Rivers

Why do you need a sleeve for your passport? I thought you only needed them for the cards that have the microchips?

Yes you need them for your card with microchips. Biometric in passports also uses RFID.. So you need to have RFID blocker to prevent identity theives from getting your personal information. 

Can you write on the sleeve with a permanent marker?

I used a Gel Pen to write on my sleeves. However, it took quite awhile for it to dry. Better idea: there's a small white square in the upper right corner of the sleeve and I put 1 letter in there as a shorthand for the credit card in the sleeve.

what are the dimensions of the credit card sleeves? In inches please?

I measured from the top of the curves on these (to allow you to grab the card in the middle and not have to dig into the sleeve to get your card out) and the credit card sleeve is just under 3.5" in length and width is exactly 2.25". Passport sleeve measures 5.25" in length and slightly over 3.75" in width.
