There is disclosed a compact wallet, comprising at least two rigid plates at least one having a channel into which an encircling elastic band is interposed to bias the at least two rigid plates inwardly and securely hold the card-like contents while providing elastic volume therebetween while allowing freedom for the dynamic extension and contraction of the band over the entire running length of the wallet. The wallet includes an auxiliary feature removably attached within the interior at least one of the at least two rigid plates interposed using a tang inserted into a recess formed inside the plate, the tang having a hook, the hook extending at an angle to the tang, the hook engaging an undercut of the recess to prevent inadvertent dislodgement of the auxiliary feature from the recess.
