hi there
i think the ones that u bought from City Super are the new packaging and the ones from PnS are the old packaging. I have a mommy in Spore that the old packaging have recd quite a lot of complains. Reason being of their flimsy packaging, (with no plastic and opening at the side of the box) there was once, my friend opened and found baby cockroaches inside! She wrote to Healthy Times in Sg, and they confirmed that they had a problem with one of the shipment (something to do with an accident and that shipment was spoiled, some cracked etc). So, they looked into it and decided to change their packaging.
