Lost lunch money happens. But maybe dollars and change will less likely be misplaced if your student stashes cash in this bright billfold. Specially designed for school kids, it sports a window for an ID card and an outside personalization pocket for fave photos. In vibrant green (shown) or purple, the wallet is very visible at the bottom of even the darkest, most jam-packed of backpacks. Modern Kids Wallet, $12 at MoMAstore.org.
