After a few months, finally the fitball just pops up in front of me while shopping at Tesco. And the price is unbelievable. It is only RM19.90. The diameter is 26 inch (65cm). Just nice for my size.
RM19.90 wor. The last I saw one, it cost more than RM50. I was wondering whether they stick the wrong price. Who cares! Quickly grab one box (it comes with hand pump too) and head to the cashier counter.
I secured myself a fitball that cost only RM19.90. :D
