co2CREA ハードトラベルケース Logitech G305 Lightspeedワイヤレスゲーミングマウス用

The co2CREA hard travel case is an EVA shell molded for exactly one device: the Logitech G305 LIGHTSPEED wireless gaming mouse. This article covers what that custom fit actually buys you, how it compares to a generic pouch, and who should not bother.

Overview

Short version: this is a tool for people who put a G305 in a bag at least once a week. If your mouse never leaves your desk, skip it.

If you carry it to LAN events, offices, or on trips, it is cheap insurance against scratched shells, flattened side buttons, and peeling mouse feet.

The shell is EVA (ethylene-vinyl acetate), the standard material for gadget cases because it is stiff and light at the same time. It resists crushing pressure from other items in a bag, and the outer fabric sheds water, so light rain is unlikely to reach the contents through the zipper.

It is not fully waterproof — submerge it and water gets in.

Only one color is offered: black, with restrained branding that does not look out of place in a work bag. The listing is for the case alone — no mouse, no USB receiver, no cable. Confirm this before you order.

Compatibility Guide

The interior is molded to the outline of the Logitech G305 LIGHTSPEED, and that is the only model the maker lists as compatible.

The benefit of a molded interior is simple: the mouse does not move. Generic pouches leave slack, so the mouse bounces around when the bag swings, and that repeated impact lands on the scroll wheel and side buttons.

Remove the travel distance and you remove most of that stress.

The drawback comes from the same design. A G PRO Wireless, a G703, or other Logitech wireless mice either will not fit or will not be held in place. If you plan to upgrade your mouse soon, budget for the fact that the case will not carry over.

That is the trade every model-specific case makes.

One practical note: the G305 runs on a single AA battery and stores its USB receiver inside the battery compartment. If you travel that way, receiver storage is a non-issue.

If you leave the receiver plugged into your PC, know that the case itself has almost no spare room for it.

Product Info

co2CREA builds molded cases for products that never got a first-party one — earbuds, cameras, handhelds, and accessories like this. That is the niche it fills here.

The price was ¥1,836 as captured on 2026-08-27 (Amazon.co.jp, ASIN B07JFZ7CLW), which is normal for an EVA mouse case.

An earlier capture on 2026-06-04 recorded ¥7,388 for the same ASIN — far too high for a case of this type, and most likely a seller change or a data error. Prices move a lot here, so check the current price and the seller on the product page before buying. If you see a figure well outside the usual range, suspect an out-of-stock third-party listing.

On ratings, the product sits at 4.6 out of 5 from 76 reviews (92% positive, captured 2026-06-04).

Seventy-six reviews is not a huge sample, but for a niche model-specific accessory it is enough to be meaningful, and a 4.6 average points to consistent reports that the fit is correct.

Even so, read a few review bodies for comments about fit or stitching before ordering. Warranty terms should be confirmed on the listing.

Alternatives

There are two real competitors: generic gadget pouches from brands like UGREEN or ORICO, and simply reusing the box the mouse came in.

A generic pouch holds the receiver, a cable, and earbuds together, which is genuinely more convenient if you want one bag for everything, and the prices are similar. The cost is slack — the mouse shifts, and metal connectors rubbing against the shell produce shine marks and scratches.

Frayed mouse feet are the other classic symptom of careless transport.

Reusing the retail box costs nothing but fails on pressure and humidity. Fine for a few trips, wrong for a weekly commute.

This case optimizes for one thing: moving a single mouse, reliably, over and over. It gives up versatility and wins clearly on that one axis.

Practical Use and Packing Tips

The most robust routine is to store the USB receiver inside the G305's battery compartment and put the whole mouse in the case. Loose receivers get lost — it is only a matter of time.

For long-term storage, remove the AA battery first. A battery left in place for months can leak, and leaked electrolyte corrodes the contacts beyond repair.

A well-sealed case also means you notice the leak late.

New EVA cases sometimes carry a material odor. Leaving the case open in a ventilated spot for a day or two after unboxing takes care of most of it.

Things to Consider

1. Wrong-model assumptions are the top failure mode. This case is built for the G305 LIGHTSPEED.

Buying it on the logic that "any small Logitech wireless mouse should fit" ends with a case that either does not close or does not hold. Check the model number on the underside of your mouse first.

2. Case only. No mouse included.

Listing thumbnails often show a mouse inside, which is where the confusion starts. Read the title and the contents description.

3. Store categories can be wrong. This item is sometimes filed under "gaming mouse" rather than as an accessory, and listing metadata such as manufacturer or model number occasionally belongs to a different product entirely.

Judge the product by the images and title, not by the category or the spec table on the page.

4. There is essentially no room for accessories. No cable, no spare battery, no bungee.

If you need to carry those, buy a small separate pouch or choose a generic case from the start — it works out cheaper.

5. Shock protection has limits. EVA handles pressure and abrasion well but does not match a rigid hard shell.

Dropping the whole bag or sitting on it can still damage the mouse.

6. Watch for price anomalies. As noted, wildly different prices were recorded for the same item.

If the displayed figure is an order of magnitude off, wait or check another seller.

Best Use Cases

• LAN party and esports regulars — if the mouse goes in and out of a bag constantly, the case directly determines how the shell looks and feels in six months.
• Travelers and commuters who game or work on a laptop — the case fixes the mouse in one spot in your bag, which makes packing easier, not harder.
• Anyone keeping a G305 as a spare — a case beats a dusty drawer for multi-year storage. Pull the battery first.
• People who lend hardware to others — a case makes borrowers handle the mouse more carefully.

It is a poor buy for desk-only users, people who want one container for all their peripherals, and anyone about to switch mice. A model-specific case locks its value to the mouse you own today.

FAQ

Q. Will a G304 or G PRO Wireless fit? A.

Only the G305 LIGHTSPEED is listed as compatible. Other models have different outlines and will likely either not fit or not stay put.

Q. Can I pack the receiver and a cable too? A.

Do not count on it — the interior is molded with almost no spare volume. Store the receiver in the G305's battery compartment instead.

Q. Is it waterproof? A.

It is water-resistant, not waterproof. Submersion will soak the contents.

Avoid an exposed outer bag pocket in the rain.

Q. Does it include the mouse?
A. No. Case only.

Q. Why does the price differ from the listing? A.

Prices are captured at a point in time and change often. The ¥1,836 cited here was captured on 2026-08-27.

Always check the current listing.

Q. Any issue with carry-on flights? A.

The case itself is ordinary plastic and unrestricted. Follow your airline's rules for any batteries inside.

The G305 uses a single AA cell.
