UJ 30ml DIY Concentrate Over the Rainbow

Step into a world of bold, vibrant flavour with UJ 30ml DIY Concentrate – Over the Rainbow. Designed specifically for DIY e-liquid enthusiasts, this playful concentrate blends a variety of sweet, tangy, and tropical fruit notes that bring to life the joy of your favourite rainbow-coloured candies. As a result, every puff offers a rich and satisfying experience that keeps you coming back for more.

Whether you’re brand new to DIY mixing or already have a favourite flavour lineup, Over the Rainbow is a fantastic addition. It delivers a beautifully layered fruit profile, combining juicy berries, zesty citrus, and a smooth candy sweetness. Consequently, it works well as a standalone flavour and also shines when paired with other concentrates, such as menthol, soda, or tropical blends.

Simple Mixing Instructions

Getting started with Over the Rainbow is easy. To mix your own e-liquid, use a ratio of 15–20% concentrate with your preferred base mix. For example, to make 100ml of finished e-liquid, simply combine 15–20ml of Over the Rainbow concentrate with 80–85ml of base mix. Shake the mixture thoroughly to ensure it’s well blended.

Furthermore, this flexible mixing range allows you to tailor the flavour strength to your taste. Choose 15% for a lighter, more mellow experience, or increase to 20% for a punchier, candy-like burst of flavour. Either way, you’ll enjoy a vape that’s smooth, fruity, and consistently delicious.

Pair with the Right Base and Nicotine Shots

To elevate your DIY blend even further, we recommend using one of our high-quality Base Mixes, available in 70/30 or 80/20 VG/PG ratios. The 70/30 base provides a great balance between vapour production and flavour delivery, making it a versatile option for most vaping setups. Meanwhile, the 80/20 mix is perfect for sub-ohm vapers who enjoy dense clouds and a softer throat hit.

Additionally, if you want to add nicotine to your e-liquid, our nicotine shots are the ideal solution. They blend easily into your mix, allowing you to achieve the perfect nicotine strength without impacting flavour. After combining all components, consider letting your e-liquid steep for a few days — this helps the flavours mature and become even more enjoyable.
