This
week we had our lucky draw following the APHM. Three lucky winners
picked up their Xeralife products. Our picture shows Alex Ng (left) and
Mr. Tasnim N., winner of the second price. While collecting the goods
from the Xeralife showroom, he had a chance to look at the latest
products from Xeralife.
