	function prefix_show_expiration_period() {
	$product_id = get_the_ID();
	$expires_after_value = get_post_meta( $product_id, 'wcmo_product_expires_after_value', true );
	$expires_after_period = get_post_meta( $product_id, 'wcmo_product_expires_after_period', true );
	if( $expires_after_value && $expires_after_period ) {
	echo 'Expires after ' . $expires_after_value . ' ' . $expires_after_period;
