This article covers ポケットWiFi用PUレザーケース【保護フィルム・ハンドストラップ付き】 (601HW — a three-piece protection kit built specifically for the Y!mobile 601HW, 602HW and 603HW pocket WiFi routers.
Overview
The short version: this is a practical accessory for people who carry a 601HW, 602HW or 603HW every day and want to stop scratches and scuffs. The material is PU leather (faux leather) and the shell is soft, not rigid — it is not engineered for drop protection.
It absorbs the everyday damage that comes from keys and coins in a bag, or from setting the router down on a hard desk.
The manufacturer is Packaging Technology and the Amazon.co.jp ASIN is B07H7Y8ZD5.
As captured on 2026-09-03, the listing showed 123 reviews at 4.2 out of 5 stars (84% favourable).
For a small accessory, a three-digit review count with a stable score is a reasonable signal — but review counts and ratings move, so check the current numbers on the product page.
A pocket WiFi router is a single point of failure: when it dies, your connection dies with it, and almost nobody carries a spare. Spending a small amount to reduce the odds of damage is sound economics.
Compatibility Guide
Supported models are the Y!mobile 601HW, 602HW and 603HW.
This is the single most important check, because the case will not fit anything else. Router cases are far less forgiving than phone cases — a few millimetres of thickness difference means it either won't go on or won't stay on.
| Check | What to confirm |
|---|---|
| Model number | Printed on the device as 601HW, 602HW or 603HW |
| Carrier | A Y!mobile unit |
| Cutouts | Charging port, power button and display line up with the openings |
| Film size | The bundled protector is cut for the 601HW/602HW/603HW screen |
These three models are different generations but share a close body shape, which is why one case covers all of them. The flip side is that it cannot be reused on a newer generation or another maker's router — a Fujisoft FS050W, for example, is a completely different size.
"It's also a pocket WiFi, so it should fit" does not hold here.
Cutouts allow you to plug in the charging cable and press the power button with the case on. Because it is a soft case, however, the router gets thicker once fitted.
If you charge on the official cradle, the case may prevent it from seating — plan on removing it daily in that scenario.
Product Info

The Amazon JP price was ￥1,480 as captured on 2026-09-03. Viewed as three items rather than one, that puts it firmly in the entry tier: a standalone screen protector and a strap would each cost a few hundred yen on their own.
Prices change often, so confirm the current figure on the product page before ordering.
The set launched around 2018 and has stayed on sale since. Long-running accessories tend to thin out in stock once the target devices age, so if you intend to keep using a 601HW-series router, buying while it is still listed is a defensible call.
Warranty is typically limited to initial-defect handling by the seller. Open the package promptly and check the fit, the stitching, and the film for dust or bubbles.
What It's Actually Like to Use
PU leather is a resin surface finished to look like leather. It is light, sheds water droplets, and keeps the price down — but over time it can peel or wear through at the corners.
If the router lives in a bag every day, treat the case as a consumable with a one-to-two-year life. Used occasionally, it will last much longer.
The bundled protector is PET film, not tempered glass. It lacks the rigid feel and impact resistance of glass, but being thin and flexible it conforms well to edges.
The finish depends almost entirely on dust removal: lift dust with adhesive tape, align in good light, then press outward from the centre to push bubbles clear.
The hand strap is quietly the most useful part. Pocket WiFi units are palm-sized with rounded corners and are easy to fumble one-handed; a strap around your wrist cuts the odds of a drop far more than a soft case cuts the damage from one.
Best Use Cases
- Daily carriers of a 601HW/602HW/603HW — Enough protection against bag rash, with almost no added weight.
- Anyone who also wants a film and a strap — One purchase instead of three, with no sizing guesswork.
- People running several identical units — Cases make family or work devices easier to tell apart.
- Owners keeping an ageing router in service — These models are no longer current; slowing cosmetic wear is a cheap way to run them out.
It is a poor fit if you want drop or water protection, if you prefer tempered glass, if you charge on a cradle without removing the case, or if your router is not one of the three supported models.
Alternatives Worth Considering
There are three realistic options: a model-specific kit like this one, a generic gadget pouch, or nothing at all. The model-specific kit wins on cutout alignment and film sizing.
A pouch carries several gadgets at once and survives a device upgrade, but you have to take the router out to use it — awkward if you check status LEDs often. Going bare is genuinely fine for a router that mostly sits on a desk: no case means slightly better heat dissipation and less bulk.
For other routers, search by exact model name; that is the only reliable way to buy a router case.
Things to Check Before Buying
The most common mistake is buying for the wrong model. 601HW, 602HW and 603HW look alike in text, and newer series exist alongside them.
Confirm the model printed on your device, or in your settings screen or contract paperwork, before ordering.
It is not waterproof. PU leather sheds droplets but carries no water-resistance rating. Wet environments need a different solution.
It is not a thermal win. Routers warm up under sustained use, and a soft cover traps some of that heat.
During long tethering sessions, leave the device somewhere with airflow — heat shortens battery life.
The PET film does not tolerate re-application. Once peeled, the adhesive picks up dust and bubbles are likely.
There is only one sheet, so take your time.
Listing data can be inconsistent. In the collected data for this product, the entry labelled "Amazon US" carries a yen price (￥1,480) and an Amazon.co.jp link, which does not add up as an overseas price; the eBay entry has no confirmed price either.
Amazon pages aggregate data automatically, so mismatches like this are common. Before ordering, verify visually from the listing images and title that you are buying a case for the 601HW series, and treat any price you see here as a captured snapshot rather than the current one.
Finally, calibrate expectations for the price. A ￥1,480 three-piece set will not match premium stitching or premium film optics.
Judged purely on "does it stop scratches," it does the job.
FAQ

A. Yes. The case is designed for all three models, and no others.
Q. Can I charge with the case on? A.
Yes, via cable — there is a cutout for the port. A charging cradle may not accept the extra thickness; test before relying on it.
Q. Is the included protector glass?
A. No, it is PET film. Thin and easy to apply, but without the hardness of tempered glass.
Q. Is it water resistant?
A. No. PU leather repels droplets but carries no rating.
Q. What does it cost?
A. ￥1,480 on Amazon JP as captured on 2026-09-03. Check the listing for the current price.
Q. How is it rated?
A. 4.2 out of 5 from 123 reviews (84% favourable) at capture time. Figures change over time.
