The scents typically last 3-6 weeks. Some scents are naturally lighter than others. The freshie itself will last much longer, however the scent will fade with time.

We are not taking custom orders at this time, however we will be sure to let y'all know once we are!

If used properly, no. Freshies can melt in extreme heat greater than 100 degrees. If you are going to be in parked in direct sunlight for awhile, it's best to move the freshie to your blinker or place back in the bag. Definitely do not ever trap your freshie between your sun shade and windshield or else it will surely melt. :)
