KOPEN Mart is actually a retail store that sells goods. KOPEN is a Malay acronym for "koperasi penjara". KOPEN Mart is also a place for parcels to be delivered and placed. The parcel did not deliver until in front of the house because sometimes it's hard for the courier to find the house by only looking at the address. The courier will inform the receiver if the parcel is already delivered so that he/she can come to KOPEN Mart and take their parcel.
