Don't lose your bills!

Attach simple clip-on holders (print at least a pair) to keep essential mail in sight, such as bills, letters, and items for later review. Frequently, crucial papers like invoices get hidden beneath a pile of Post-It notes in an in-tray - only to be forgotten.\r\n\r\nAll you need is a wall or vertical surface, attach a pair of these clip-on holders with double-sided tape, and they'll securely hold your vital documents until you address them.
