The Serafin 25s JW101 F2 is a powerful, visually striking firework cake produced by Jorge, designed to combine strong pyrotechnic effects with elegance and vibrancy. This fireworks battery stands out for its substantial 30mm calibre, delivering 25 impressive shots that develop high in the sky and create a dynamic, eye-catching display. Falling into category F2, Serafin JW101 F2 is suitable for outdoor events where an expressive show is desired without resorting to the even stronger F3 category.
Its classic straight firing pattern ensures that every effect rises vertically, showcasing vivid corolla bursts that transition into colourful stars with prominent comet tails. Serafin’s show features a refined progression of green, yellow, red, purple and blue stars, maintaining a well-ordered and visually consistent spectacle. With an operation duration of around 30 seconds, this model is ideal for delivering a memorable main display in a concise time frame, making it well-suited for New Year’s Eve, weddings, outdoor parties, birthdays or special occasions calling for a strong solo firework cake or a centrepiece within a larger sequence.

What should you consider when choosing this firework cake?
Understanding the technical aspects of Serafin 25s JW101 F2 helps you gauge the experience it will deliver. The 30mm calibre ensures each shot reaches a significant height and produces large-scale stars, setting it apart from standard batteries with smaller tubes (16–20mm). With 25 shots and an approximate run time of 30 seconds, Serafin offers a concise yet impactful show – ideal if you need a strong highlight or want to coordinate it with other fireworks for a balanced display. As a category F2 product, it is intended for responsible adult use with all the standard safety precautions: ensure a stable, flat base away from obstacles, and always follow the supplied instructions.
When is Serafin 25s JW101 F2 a good choice?
This firework cake is a popular option for organisers who wish to deliver a prominent, colourful sequence – whether as a standalone centrepiece at smaller celebrations or as one of the premium elements in a larger pyrotechnic event. Since Serafin features a straight, I-shape firing pattern, it works exceptionally well in open spaces where vertical effects are most appreciated and safe distances can be maintained.
