This is a great idea that will delight the teams in your referring offices. Winter can be harsh and cold so pamper teams with a little gift bag filled with a bouquet of lip balms and cute clip-on lip balm holders that they can attach to their keychain or purse.
All different kinds of holders are easily found on Amazon. The one pictured is at this link!
For lip balms, you could go with basic Chapstick, or upgrade to something like Burt’s Bees. For some of your top referring offices, you might want to splurge with Body Shop or Bath and BodyWorks products.
