Our story
From a small pharmacy
to a nationwide inspiration
The shop's Company Profile tells how it grew from a pharmacy and souvenir business into stores across the country, in three steps. It gives no years, so they are shown as a story rather than a timeline.

A small pharmacy on Koh Samui
Chang Siam 100 Baht began as a small community pharmacy on Koh Samui, Surat Thani. That small start grew from a commitment to choosing good, quality products at fair prices for Thai customers and international tourists alike.
The Mix & Match concept
We then developed the Mix & Match concept: a souvenir shop that brings together Thainess, fun and quality products at comfortable prices, where customers can shop to their heart's content in a modern, friendly setting.
Stores in key tourist destinations
With the support of our customers and team, we expanded from Koh Samui to key tourist destinations across the country, and became one of the souvenir shops that travellers from around the world make a point of visiting.
