Australian Souvenir Tie Clip Size (approximate) 5mm (height) x 50mm (width) x 15mm (depth) The stone part is probably opal. This is a new, unused item. Please note that there may be some damage to the case due to aging, and slight dullness on the tie clip itself. It will be placed in an OPP bag and shipped with thorough waterproof measures, so please rest assured. I am also selling opal necklaces, tie clips, and many other items. ■ If the items can be shipped together, we will discount 50 yen from the second item onwards! Please send a message in the comment section before purchasing. ☺︎
