I recently sent my oldest off to sleepaway camp, and in addition to finding just the right hiking boots, duffel bag and shower caddy, I wanted to find the best way to label it all. A good friend pointed me in the direction of Name Bubbles, which are sticky labels that once applied stay stuck on clothes, shoes and toiletries through just about anything - they're laundry and dishwasher safe as well as bug repellent and sunblock proof. They're also freezer friendly, and will stick through -60 F.
Name Bubble has labels for all needs, including a Camp Labels Pack ($38.88) which has over 100 labels in a variety of sizes and styles. I received a pack of these labels, which were more than we needed to label every last item my daughter brought to camp - with a few leftover, too.
medical labels, and more. My daughter is back from her sleepaway camp adventure, and so is her stuff... and all the Name Bubbles labels are perfectly intact, too.
