Somjai Stationery (Siam Square)

Somjai is the beloved, old-school stationery shop that generations of Thai students have relied on before every new term. Tucked inside Siam Square, it packs aisles with everyday essentials at prices that feel frozen in time. Expect racks of gel pens, mechanical pencils, correction tape, rulers, math sets, sturdy clear folders, and classic Thai-brand supplies that hold up through a busy semester. It’s also a goldmine for small, giftable items like pastel sticky notes, cute erasers, and inexpensive planners, perfect for souvenirs that won’t weigh down your suitcase. Staff are used to back-to-school rushes and know where everything is, so don’t hesitate to ask. If you want maximum utility for minimal baht, start here, stock up, and build the rest of your haul around Somjai’s unbeatable basics.
