People compare them constantly. Almost nothing about them is the same: the material, the price, the way each one is used, and the idea each has of what a bag is for.
What they share: a silhouette
The comparison is not unreasonable. The jelly firkin borrows the grammar of the classic leather city bag — a trapezoid volume that stands up on its own, a notched flap, a lock-style closure, two rounded top handles with visible stitching. That architecture is what the eye recognises, and it is why the name stuck.
The resemblance ends there.
The material: leather against TPU
A traditional leather bag is a living surface. It takes a patina, it needs feeding, it can be repaired, and it fears water.
The Jelly Firkin is made of frosted TPU — thermoplastic polyurethane, the material used for technical equipment. It does not develop a patina; it catches light. Rain, sand and splashes are non-events. And it lets people half-see what you are carrying, which no leather will ever do.
TPU is not the same thing as PVC, and the difference is worth knowing if you have owned a cheap clear bag before. TPU stays supple, it does not yellow the way PVC does, and it holds up to cold and to abrasion.
Upkeep follows from the material. Leather is fed and conditioned on a schedule. A jelly firkin is wiped with a damp cloth and put away.
This is not a cheaper substitute. It is a different proposition.
Price: two different worlds
A leather bag from a major house is counted in thousands of euros, with waiting lists and a resale market attached to it. The jelly firkin is counted in tens: €53.90 for our signature model. Shipping is free, and the displayed price is the price paid, taxes included.
That gap is not only a budget question. It changes your relationship with the object. A €53.90 bag goes to the beach, to a festival, out in the rain. You do not protect it. You use it.
How each one is used: discretion against display
The classic leather bag is built on timelessness and discretion. It is designed to be read slowly, by people who already know what they are looking at.
The jelly firkin does the opposite. The translucent material turns whatever is inside into part of the outfit: a paperback, sunglasses, a set of keys, a bright charm — all of it visible, and all of it deliberate.
That is a large part of why it works for a generation used to showing its day as it happens. The bag no longer hides. It tells.
Is a jelly firkin a fake?
No. The distinction matters, and it deserves a straight answer rather than a shrug.
A counterfeit copies a brand: its name, its logo, its distinctive signs, in order to pass itself off as authentic. A jelly firkin carries no logo, no name and no distinctive sign belonging to any other house — nothing stamped, embossed, printed or engraved. What it takes up is a silhouette, and a silhouette belongs to the common vocabulary of bag-making, in the same way the double-breasted jacket and the pleated front belong to the common vocabulary of clothing. Shapes circulate. Names and logos do not.
The practical test is simple, and it works on any listing you are looking at. Check the bag, the hardware, the lining, the dust bag, the box and the wording of the listing itself for a luxury house's name or logo. If a seller offers you a bag carrying one, it is not a jelly firkin — it is a counterfeit. Buying one carries real consequences: customs can seize the item at the border, and in several countries the buyer, not only the seller, can be fined.
We sell under our own name, La Firkin, from Lausanne in Switzerland. Nothing on our bags claims to be anyone else's.
Which one should you buy?
The question barely arises, because the two are not competitors.
A leather bag is a long-term investment to be looked after. A jelly firkin is a seasonal accessory: coloured, water-resistant, chosen to match what you are wearing rather than what you earn. Many of our customers own both and do not take them out on the same days.
Within the range, the Jelly Firkin (€53.90) is the full silhouette, in twelve colours from Cherry and Sunset to Onyx and Pearl. The Mini Jelly Firkin (€45) is the same twelve colours in a smaller format. The Jelly Croco (€53.90) adds a croco-textured finish in five colours, and the Baguette Firkin (€49.90) is the shoulder shape, in four.
Orders are dispatched within 24 working hours and arrive in four to nine working days depending on the country, tracked, with shipping included. We deliver to the United States, the United Kingdom, Switzerland, France, Belgium, Germany, Spain and Italy. Returns are accepted; return postage is paid by the customer.
What if you want both?
Since autumn 2026 there is a third answer: the Maison now makes leather too. Le Firkin takes exactly the silhouette described above — flap, padlock-style clasp, round topstitched handles — in full-grain cowhide leather, lined in leather, at €99.90.
Full grain means the top layer of the hide, the one that carries the natural grain: neither sanded down nor covered with a film. It is the most hard-wearing part of the leather, and the only one that truly takes a patina — the difference between a bag that ages and a bag that wears out.
Everything in this comparison still holds for it: that leather fears water, it is fed twice a year, and it shows nothing of what it carries. It simply does not have to cost thousands of euros to be real leather.
And for anyone who wants the depth of a grain without the leather, Héritage offers an embossed reptile grain in nine autumn shades, at €69.90.
