This gemfive really one of a kind one, I ordered some baby stuff on 1-Feb but until now still not yet shipped. Since my waifu marah me as she needs to use immediately already and there were no shops nearby selling the item, I decided to buy from the other 3 sites simultaneously on monday 4pm and below is the result:-

lazada - received on tuesday morning!
11street - received on wednesday
babydash - received on wednesday

Meanwhile here is the answer from gemfive CS:-

"Thank you for contacting GEMFIVE!
As we checked, the delivery normally takes 8-10 working days."
