What is エチケット袋（１回分）?
Meet the エチケット袋（１回分） — Daiso's single-use sickness bag, made right here in Japan. At just ¥110 (roughly $0.70), this compact little lifesaver measures a surprisingly practical 13cm × 0.6cm × 26cm and folds flat enough to slip into any pocket, wallet slot, or toiletry pouch without a second thought.
The material combination is where things get genuinely clever: the outer layer is PE (polyethylene) film for a leak-proof seal, while the interior is loaded with a high-polymer absorbent — the same superabsorbent technology used in modern diapers. When you use it, the contents are rapidly solidified and odor is locked in. No mess. No smell. Just discreet, dignified containment. The product is explicitly designed for motion sickness on vehicles and alcohol-related nausea, but its engineering doesn't stop there.
It ships as a single bag per pack, which keeps the price point ultra-low and makes it easy to grab several at checkout without any guilt. The absence of a printed pattern or color variation (no assort options) keeps it minimal and — importantly — inconspicuous. Tuck it in your travel bag and forget it's there until the moment you're incredibly grateful it is.
How to Use It — Hack Ideas
Primary Use: Keep one in your carry-on or glove compartment for travel days. Winding mountain roads, turbulent flights, long ferry crossings, or a big night out — this bag handles the aftermath quickly and with zero fuss. The polymer gel works fast, so cleanup is as simple as sealing and disposing.
Hack #1 — Diaper Bag Emergency Backup: Parents, take note. The same polymer technology that handles motion sickness works brilliantly as an emergency diaper disposal bag when a proper bin is nowhere in sight. The odor-locking seal is genuinely impressive for such a small item.
Hack #2 — Wet Umbrella or Swimsuit Containment: Caught in a sudden shower? Slip a soaked umbrella head or a damp swimsuit into this bag after a beach day. The PE lining is fully waterproof, and the compact folded form means it takes up almost no space in your bag until you need it. It won't absorb the water the same way (you'd need the polymer activated), but as a leak-proof containment sleeve, it works perfectly.
One bag costs less than a piece of candy. Stock up on three or four and distribute them across your travel kit, car, and kid's school bag.
Reviews & Verdict
User sentiment around Daiso's travel gadget range is overwhelmingly positive — the brand has built a loyal following among budget-conscious travelers who appreciate finding genuinely functional items at a fraction of pharmacy prices. The etiquette bag fits squarely into this category. Reviewers who've tested similar polymer-based sickness bags consistently highlight the no-leak, no-odor performance as the standout feature, noting it far outperforms basic paper or plain plastic bags.
The Japanese-made quality distinction also earns trust — this isn't a product where you want to take chances on construction. The PE seam integrity and polymer activation both hold up reliably, which is exactly what you need in a high-stress moment.
The one caveat worth flagging: it's a single-use item. If you're prone to travel sickness on longer trips, buy multiples — one bag won't cover a full travel day. At ¥110 per unit, buying four or five is still cheaper than a single-use alternative at any airport convenience store.
For occasional travelers, parents, designated drivers, and anyone who's ever been caught unprepared on a winding road, this is a quiet, unassuming gem that earns its shelf space ten times over.

Value Score: 78/100
Solid price-to-quality ratio anchored by real polymer-absorbent engineering and Japanese manufacturing standards — but the single-unit-per-pack format and single-use nature cap the practicality score, making it best purchased in multiples to truly unlock its travel value. Great value, worth every yen.
