The twins told the Wall Street Journal that the carryall in question was made using a Bombé technique, which they say is "an older [one] that you don't see very often." Plus, the lining of the bags are made from linen, as opposed to manmade fabrics. "That [backpack] was obviously a very special bag to us, but that didn't represent the entire range," Mary-Kate added.
If that still doesn't seem like a good enough reason to throw away a year's salary for something you carry your lipstick in, the Olsens assure us that their range of leather goods aren't all so expensive. They make a point to mention that many of their bags will cost you between $1,000 and $3,000, so even the mildly rich can score one of their coveted carryalls.
Thank goodness for small #blessings.
