BẾN TRE COCONUT SWEETS!

28,000 VND ⭐⭐⭐⭐✰

If you like eating sweets and want to try Vietnamese local specialties, you should visit Bến Tre and get yourself some coconut sweets.
Coconut milk and malt syrup are the main ingredients to make this food. They also add some extra flavours to the sweets in order to produce different tastes for different people. Taste one and you can feel it melt in your mouth with all the flavours. However, the biggest problem is that it easily causes tooth decay. I will give it 4 stars.

COCONUT OIL FOR HAIR

150,000 VND ⭐⭐⭐✰✰

I bought this bottle of coconut oil a month ago, and I would say it’s a fantastic product for hair. They make this with 100% natural ingredients so that it’s safe and healthy for your hair and skin too.
