Verified Purchase

Damaged during shipping process.

The shipping %26 packaging of the item was very poor. The exterior cardboard box was intact, however, when opened the bag of magi-Cal plus had a gaping hole at the bottom of the bag. The bag was rolled and taped to prevent further loss after approx. 25% of the bags contents were gone. I have no problems with the product just its handling and delivery.
