On TikTok, videos follow one after another of translucent candy-colored bags, carried by hand like real collector’s items. Rigid handles, structured flap, small padlock: the silhouette is fiercely reminiscent of that of the legendary Birkin, but the material shines like a beach toy. In just a few weeks, this newcomer has invaded fashionistas’ feeds and the arms of Korean idols. There remains one question that everyone is asking: what is this famous Firkin bag that we are talking about everywhere this summer 2026?
Behind this name hides the Jelly Firkin, a large transparent or translucent plastic shopping bag, very directly inspired by the Hermès Birkin. Its nickname comes from the contraction of fake and Birkin, to designate a bag which takes up the codes of luxury in a colorful, light and assumed version.
Jelly Firkin: the transparent Firkin bag that revisits the Birkin
Made of PVC or TPU jelly, the Firkin bag offers transparency of around 70 to 80% depending on the model. We can see everything it contains, but with a slight blur that leaves an element of mystery. Its shape takes up the lines of the Birkin: rectangular base, double handle, flap with straps and sometimes decorative padlock, all in a format often around 35 to 40 cm designed for everyday wear.
In terms of colors, we are far from the classic shades of luxury leather goods. Bubblegum pink, electric blue, sunny yellow or candy purple transform the Firkin into the focal point of the silhouette. And then there is this jelly aesthetic which recalls the plastic sandals of childhood and the holidays of the 2000s. After the Wirkin imagined by Walmart, which already took up the codes of the Birkin, the Firkin pushes the exercise further with a pop and regressive dimension.
Why the Firkin bag is the it-bag of summer 2026
On social networks, “what’s in my bag” videos are converted into “what’s in my Firkin”, where the content becomes an integral part of the look: colorful lipstick, novel of the moment, big sunglasses, designer card holder. Demand for these jelly bags has exploded, with an estimated increase of more than 1,000% in one week on some sites. In Korea, where the trend originated, these PVC or TPU bags sell for between 20,000 and 80,000 won, or around $15 to $55.
The Firkin is part of the dupe culture: the desire to have fun with the codes of luxury without trying to deceive anyone. We don’t hide that the bag is plastic, we play with it. Where the Birkin cultivates rarity and exclusivity, the Firkin focuses on accessibility, humor and second degree. Because basically, wearing a completely transparent fake Birkin is also a way of saying that status is no longer the only priority.
How to adopt the Firkin bag: colors, sizes, maintenance
To choose your Firkin, a few criteria matter. PVC is more rigid and very shiny, ideal for a strong showcase effect. TPU remains softer, often with a frosted finish that feels a little more luxurious, but it generally costs more. Some specialist brands offer models for around £140 to £180, while simpler versions are available at low prices on marketplaces.
Size also plays a role: a 35 cm is suitable for the city, a 40 cm accommodates a computer and folder for the office or the train. To find your way around, you can rely on three simple benchmarks:
- Color: pastel for a soft look, neon for a confident Y2K look.
- Level of transparency: very clear if you want to show everything, frosted if you prefer to suggest.
- Practicality: check the weight, rigidity and the presence of an interior pocket.
Style-wise, many slip in a small opaque case for intimate objects, then focus on photogenic accessories: book with graphic cover, colorful phone case, body mist. For maintenance, a soft cloth and a little soapy water are sufficient, avoiding sources of direct heat. A slight smell of new plastic may be felt when opened, but it generally disappears after a few hours in the open air.
What exactly is the Firkin bag?
The Firkin bag, or Jelly Firkin, is a large tote bag in transparent PVC or TPU, inspired by the shape of the Hermès Birkin, available in pop colors and designed as a playful dupe.
Why has the Firkin bag become trendy this summer?
It’s a hit thanks to TikTok, the K-pop idols who have adopted it and its much more accessible price than that of a Birkin, while still retaining its iconic design codes.
How to wear a Firkin bag every day?
We wear it as a statement piece: with jeans and a blazer for the city, over a swimsuit and a sarong at the beach, or with a mini-dress and boots for a festival.
