“So glad my wife and I were introduced to Sandbox. I really like the ability to attach a photo at the end of the letter. Our son has commented that he really enjoyed the photos we’ve sent over the weeks. This app is great as it allows for tracking and if I get my letter in on time he gets it the next day. Additionally, the prepaid, self-addressed envelope is a plus and makes it super easy to get a return letter. My wife and I look forward to his return letters and keeping us abreast of how basic training is going.”

“Sandboxx is amazing! My son gets his letters within a day or two and loves it. Being able to send him a response to his letter right away is huge, especially if he sounds homesick. When I know he has a difficult week coming up I will send inspirational quotes every other day to get him through the week.”
