Fantastic romantic prop.
These bags were actually purchased as a plan "B"  Stupidly, I did not look on Amazon first, but instead went to Etsy.  This decision resulted in my original choice being shipped from Singapore, with an arrival date two days after I had planned on proposing.  As my intended's family was in on the plan, and we were going out of town, this wouldn't work!  These bags arrived on time, and were absolutely perfect!  I wasn't sure as the bags were white, but once lit and in a dark setting, only the message was visible.  Thankfully, she said yes!  She also said that it was quite memorable, and "perfect."
