We’re teaming up with Pencils of Promise to build a school in Guatemala! All month, when you purchase products in the Birchbox Shop, 15% of the proceeds will go to Pencils of Promise. To kickstart the campaign we'll unlock a promo code to use in the Birchbox Shop if this gets 500 retweets by Monday! (We'll share the code via Twitter and Facebook).
