Leather goods brand Epoi and select boutique Sister announce a collaboration featuring ruffle shoulder bags and key charms, available for preorder and exhibition.

Epoi and Sister have announced a new collaboration featuring the 'Epoi × Sister One Shoulder Bag with ruffle' (71,500 yen) and the 'One Shoulder Bag' (63,800 yen), along with a 'Key charm with ruffle' (12,980 yen).

This partnership combines Epoi’s dedication to quality craftsmanship with Sister’s cultural perspective and fashion sensibility. The result is a medium-sized one-shoulder bag designed for both aesthetic appeal and daily usability.

The bags use the 'MM' series material, combining Epoi’s original embossed leather with a PU backing. For this collaboration, shoulder and side panels have been accented with smooth leather for a more refined look.

A bold 'ruffle' motif, a signature of Sister’s collaborative products, has been added to the shoulder strap as an accent.

Two types are available: the glamorous 'ruffle shoulder type' (71,500 yen) and the more minimalist 'simple shoulder type' (63,800 yen). A matching key charm (12,980 yen) completes the collection. *All prices include tax. Material: Cowhide (North American embossed × Italian smooth). Color: Black.

An exhibition and order event will be held at the Epoi Omotesando main store from June 5 (Fri) to June 8 (Mon), 2026.
