Ace's No.1 Selling Suitcase! Reasons Why the Front-Opening x Trunk-Style Suitcase 'Proteca FULLESTER EX' is Supported

The Proteca 'FULLESTER EX' is gaining support as a suitcase that is easy to use in limited spaces such as during transit or in hotel rooms.

With features like a front-opening design, trunk-style storage, and expandable capacity, it meets the demands of modern travel and has become the No.1 series in sales among the 270 suitcase series currently offered by bag and luggage manufacturer Ace Co., Ltd. (as of the end of May 2026).

We introduce the reasons why it is chosen by many travelers, along with its product features.

[Product Features] Reasons why FULLESTER EX is supported

Front-opening design for easy access to luggage

'FULLESTER EX' is the first Proteca series to adopt a front-opening design, allowing access to the main compartment from the front.

The carry-on size features a 'vertical opening' that allows you to take out luggage while standing upright at airports and stations, while the checked baggage size features a 'horizontal opening' that allows for space-saving opening and closing even in compact rooms.

Trunk-style for easy storage of bulky items

The checked baggage sizes (No. 01553, 01555) adopt a thick-gusseted, vertical trunk style.

With a single main compartment, bulky items can be stored together. Despite its large capacity, it is easy to load into a car and has a shape that takes up less space when the suitcase is laid down.

Expandable function for peace of mind when luggage increases

During trips, luggage tends to increase due to souvenirs, etc. 'FULLESTER EX' is equipped with an expandable function that allows you to increase its capacity.

It can increase capacity by about 10L, equivalent to about one night's worth of luggage, providing peace of mind when your luggage increases during your trip.

Proprietary development features to support comfortable travel

It is equipped with 'Silent Caster®' and 'Bearon Wheel®' for quiet and smooth rolling, and the patented 'Magic Stop®' that allows you to fix the wheels with a switch at hand.

Furthermore, the ergonomically designed 'Ergonomic Handle' reduces the burden during travel and supports a comfortable journey.

High-quality design suitable for both travel and business trips

The body shell features a rib line inspired by the groove 'Hi' on a Japanese sword's blade, enhancing its strength.

With a metallic hairline finish, it offers a high-quality impression suitable for both travel and business trips.

Quality and after-care that brings peace of mind to your travels

Proteca suitcases are manufactured domestically under strict quality control at our Akabira factory in Hokkaido.

As a service to support peace of mind after purchase, we offer 'Proteca Premium Care,' a 3-year, unlimited free product warranty that also covers damage by airlines. After the Premium Care period, a 7-year product warranty is provided, offering a total of 10 years of support. You can travel with peace of mind.
