ZUS Malaysiaku Tumbler 470ml (16oz) - Spare Part - Lid

I've had to replace the lid of my tumbler three times since purchasing it. The first replacement was free from ZUS due to a spillage issue. The second time, I had to purchase a new lid because the original one broke and could no longer fully close after extended use. However, ZUS sent me a defective lid, and I had to arrange for them to send a replacement - the third lid. At this point, I'm uncertain how long it will be before I need to replace the lid again.
