Lost property

Inquiries regarding lost property should be primarily sent to individual student organisations. Lost property left in HYY premises (e.g. meeting rooms, saunas etc.) may be delivered to the HYY Services Office. If lost property is not collected, it will end up in recycling. Ask for your lost property as soon as possible.
