Product Description

The SEEU Longfill E-Liquid Kit is everything you need to create a full 60ml of premium, personalised vape juice — all in one complete package. Developed by SEEU Future Juice, each kit contains a 60ml bottle pre-filled with 5ml of double-concentrated flavour, paired with a separate SEEU Nic Shot (10ml 20mg) and a SEEU Booster Shot (30ml VG/PG nicotine-free base) — so you have complete control over your nicotine strength and PG/VG ratio from the moment you open the box.Think of it like a premium flavour cordial: intensely concentrated, packed with authentic taste, but designed to be mixed before vaping. Once you add the nic shot and booster shot to the 60ml bottle and shake, you have a full, ready-to-vape e-liquid tailored exactly to your preference — no calculations, no guesswork, no separate purchases required. A 60ml longfill bottle delivers up to 18,000 puffs — equivalent to 30 disposable vape bars — making the SEEU Longfill Kit one of the most cost-effective and environmentally conscious ways to enjoy premium flavour vaping without the ongoing cost of replaceable disposables.With 10 carefully crafted flavours available, the SEEU Longfill range brings the same bold taste profiles found in the SEEU 60ml Nicotine Salt Finished E-Liquid — now in a flexible, customisable kit format that puts you in full control.

What's Included in Each SEEU Longfill Kit

• 1 × SEEU 60ml bottle — pre-filled with 5ml of double-concentrated flavour concentrate
• 1 × SEEU Nic Shot — 10ml, 20mg nicotine salt
• 1 × SEEU Booster Shot — 30ml VG/PG nicotine-free base (70VG/30PG)

Simply add both the nic shot and booster shot into the 60ml bottle, seal, and shake for 2-3 minutes. Your SEEU Longfill is ready to vape.

Flavour Profile Overview

The SEEU Longfill flavour range covers five distinct taste directions, each formulated as a double-concentrated base that delivers authentic, bold flavour:

1. Kiwi Passion Fruit Guava

A vibrant tropical blend with a layered fruit profile. Kiwi brings a tangy green note, passion fruit adds a bright exotic twist, and guava rounds it out with a soft juicy sweetness. This flavour is ideal for customers looking for a lively all-day tropical nicotine salt option.

2. Cherry Tobacco

Cherry Tobacco combines sweet red cherry notes with a deeper tobacco base for a fuller, more mature flavour profile. The result is balanced rather than overly sweet, making it a strong choice for customers who prefer fruit-tobacco blends with more body.

3. Elderflower Lemonade

A fresh and lightly floral blend with sparkling citrus character. Elderflower adds a smooth aromatic lift, while lemonade keeps the profile crisp, clean, and refreshing. This flavour suits customers who enjoy brighter botanical and citrus-inspired e-liquid styles.

4. Red Warg

Red Warg delivers a bold berry-led profile with a juicy, candy-like edge. The flavour feels vibrant and punchy without losing balance, making it a good option for customers who enjoy sweeter fruit blends with strong flavour presence.

5. Blue Razz Lemonade

Blue Razz Lemonade combines blue raspberry sweetness with a sharp lemonade finish. The profile is fruity, tangy, and highly expressive, making it one of the most recognisable modern flavour directions in the nicotine salt category.

6. Forest Berries Ice

A cool mixed-berry blend with added icy freshness. Dark berry notes create depth, while the cooling layer gives the flavour a crisp finish. This option is well suited to customers who want a fruit profile with a cleaner and colder aftertaste.

7. Siberian Black

Siberian Black has a darker grape-inspired profile with a richer and more intense flavour character. It feels fuller and deeper than lighter fruit options, making it a good match for customers who prefer bold, darker-toned e-liquid flavours.

8. Dragonfruit Banana Cherry

This is a more complex fruit blend that combines tropical dragonfruit, soft banana, and bright cherry. The flavour profile is rounded and expressive, offering a multi-layered taste experience for customers who want something less common than standard single-fruit blends.

9. Summer Blaze

Summer Blaze brings together sweet citrus and stone-fruit style notes in a bright, juicy profile. It feels energetic and summery, making it a strong option for customers looking for a warmer, fruit-forward flavour direction.

10. Cactus

Cactus offers a fresher green fruit profile with a clean and slightly crisp finish. Compared with sweeter blends, it feels lighter and more refreshing, making it a useful choice for customers who want a more distinctive and less sugary flavour style.

Why choose SEEU Longfill Kit?

For wholesale buyers, the SEEU Longfill Kit solves the biggest barrier to longfill adoption: complexity. By including the nic shot and booster shot inside every kit, SEEU removes the need for customers to source additional components separately — making the product as accessible as a standard 10ml bottle while delivering 18,000 puffs of premium flavour at a fraction of the cost.
Longfills offer an economical advantage over using traditional premixed 10ml e-liquids or shortfills — and with the convenience of carrying one 60ml bottle that keeps you going for weeks instead of juggling multiple smaller bottles, the value proposition is clear to any customer. 
For retail buyers, the SEEU Longfill Kit also creates a natural product ladder alongside the SEEU 10ml 20mg Nic Salt range — allowing retailers to serve both customers who want instant ready-to-vape convenience (10ml) and those who want better value and customisation (Longfill Kit) under the same trusted SEEU brand.
The 10 SEEU Longfill flavours — including exclusive profiles like Red Warg, Summer Blaze, and Siberian Black — give wholesale buyers a range that is genuinely differentiated from generic longfill options on the market, backed by a brand identity and flavour philosophy that customers can connect with.
