WOW, this is a lot of 12  (6-2pks) of halogen bulbs.  These are 35 watt  12 volt JC type halogen with a G4  6.35 base.  These are used in many applications including undercounter and showcase lighting as well as many outdoor lighting and marine applications.  In each lot you receive  6 packages. Each card or package contains 2 lamps.  This makes the bulb total count of 12.  You could pay as much as $20 for these at retail but I bring these to you for only $5.95 + shipping to anywhere in the United States.  I have 50 watt in these also.  Check my store for other types and wattages of halogen bulbs. If you would like a larger quantity just check out my store..
