Best Tau Sar Piah in Phuket - Keng Tin

This is a very small pastry which I first had at Keng Tin in Phuket Old Town. I was then at Phuket Tea Station and found that they sold pastries which were baked by Keng Tin.

What they are specifically I am unsure - but here it is in Thai. But they do seem to be similar to a shop in Singapore called Loong Fatt?
