The two women reportedly unpacked four high-end sex toys and hid them in their clothing at an adult superstore in Perth's Northbridge.

One of the four best selling vibrators was valued at $280.

The shop owner claimed that one woman unboxed the vibrator when he entered the busy store alone. She later returned with a friend to grab more items.

The duo picked three other vibrators priced between $85 and $140 and went into the changing room.

The shop owner has offered $50 voucher for anyone who can identify the women after police released their images caught on CCTV.
