Opposite several T1 domestic gates, Lock & Lock is the plastic kingdom
On the T1 side of Tan Son Nhat, Lock & Lock sits in the domestic terminal retail strip, selling the same Korean-brand containers and drinkware you see downtown. Expect mid-range pricing: small lunch boxes around 120,000–180,000 VND, larger storage sets pushing 400,000 VND. It’s all post-security, so you can grab something after clearing checks and still make a 30‑minute boarding call.
The shelves lean hard on food storage and travel drink bottles: BPA‑free containers in 3–5 piece sets, shaker bottles in the 500–700 ml range, plus some 1‑liter thermal flasks that actually make sense for long bus rides after landing in another city. Compared with generic souvenir stalls in T1, quality is better but prices sit 20–30% above street-level supermarkets in Ho Chi Minh City.
If you cook a lot at home, this is a decent spot to top up on container sets without dealing with city traffic; just know that a similar Lock & Lock box might be 20,000–40,000 VND cheaper at VinMart downtown. Stock is mainstream: clear boxes with blue or gray lids, a few pastel colors, and some cookware odds and ends like fry pans and silicone utensils.
Plan 5–10 minutes to browse; it’s a quick in‑and‑out stop. Tip: check weight if you’re near your baggage allowance, as a bundle of glass containers can add 1–2 kg fast.
