Diy E Juice
Two DIY hobbies live in this category: coil building and e-liquid mixing. Coil wire, tools, and refill bottles are steady stock. Flavor concentrates and mixing components rotate in and out depending on availability, so what's above reflects what's genuinely here right now.
If you build your own coils on a rebuildable atomizer, our Kanthal and resistance wire cover .20 through .30 gauge, and ceramic-tipped tweezers make adjustments safer. If you're mixing your own e-liquid, unicorn bottles are the standard for both refilling from bulk juice and storing a finished batch. There's a full wire gauge guide and a rundown of what DIY mixing actually involves further down this page.
New to either hobby? Coil building isn't the place to start if you're new to vaping generally, a pre-built pod system is safer first. Not building or mixing at all? Browse ready-made Vape Juice instead.
- This category covers two different DIY hobbies: coil building and e-liquid mixing. Not every item fits both.
- Flavor concentrates and mixing components rotate in and out of stock, so check what's currently available.
- Unicorn bottles are useful for both refilling from bulk juice and storing your own mixes.
- Wire gauge determines resistance: higher numbers for mouth to lung, lower numbers for sub-ohm.
- If your device uses pre-built coils, you can skip the wire and tools entirely.
What's In This Category
Two different hobbies live under one roof here, and it's worth knowing which is which. One side is coil building: wire, tools, and the supplies for vapers who wrap their own coils on a rebuildable atomizer. The other is DIY e-liquid mixing: flavor concentrates and components for building your own e-liquid from scratch, when those are in stock.
We're telling you this upfront because what's available in each half varies. Coil wire and refill bottles are steady stock. Flavor concentrates and mixing components come and go depending on what we've got in. Check the current listing above rather than assuming everything mentioned here is sitting on the shelf today.
Refill Bottles: The Unglamorous Essential
A unicorn bottle is a soft squeeze bottle with a narrow tip, built specifically for controlled refills. Squeeze gently and you get a thin, steady stream instead of a splash, which matters more than it sounds like it should the first time you're refilling a tank over your keyboard.
They're useful in two directions. If you buy juice in larger bottles, decanting into a few unicorn bottles makes day-to-day refills far tidier. And if you mix your own juice, they're the standard container for storing a finished batch once it's done steeping.
Coil Building Wire and Tools
If your device takes pre-built replacement coils, skip this section, you won't need any of it. This side of the category is for vapers running rebuildable atomizers, where you wrap and install your own coil by hand.
Kanthal wire is the standard starting point. It's an iron-chromium-aluminum alloy that's forgiving to work with, holds its coiled shape well, and heats predictably, which is exactly what you want while you're still learning to judge coil resistance by feel. Twisted Kanthal specifically gives a bit more surface area than a single strand, which some vapers find improves flavor and vapor production.
| Gauge | Wire Thickness | Typical Use |
|---|---|---|
| .20 Gauge | Thicker | Lower resistance, sub-ohm builds, higher wattage |
| .24 Gauge | Medium | A versatile middle ground for most builds |
| .28 to .30 Gauge | Thinner | Higher resistance, mouth to lung builds, lower wattage |
Alongside wire, a good pair of ceramic-tipped tweezers is worth having on hand. Ceramic tips don't conduct electricity, so you can adjust and pulse a coil while holding it without risking a short. It's a small tool that solves a real problem the first time you build without one and accidentally bridge two coil legs with metal tweezers.
Not Building Coils? You Probably Don't Need That Half of This Aisle.
Pre-built coils and pods cover most vapers. Check our hardware range instead.
Mixing Your Own E-Liquid
When flavor concentrates and mixing components are in stock, this is also where you'll find them. DIY mixing is a genuinely different skill from coil building: instead of shaping wire, you're combining unflavored PG/VG base, a flavor concentrate, and nicotine base at the right ratios, then letting the mix rest so the flavors settle and round out, a process called steeping.
It's a hobby with a real learning curve. Getting concentrate percentages wrong can make a mix taste thin or overwhelmingly artificial, and nicotine base needs to be handled carefully and measured precisely. If you're new to mixing, start with a small test batch in a unicorn bottle rather than committing a full 100ml to a recipe you haven't tried.
Why Buy DIY Supplies from West Coast Vape Supply?
Coil wire, nicotine handling, and battery safety are places where cutting corners genuinely matters. Poor quality wire builds inconsistently and can fail unpredictably, and nicotine base needs to be exactly what the label says. Every wire, tool, bottle, and concentrate here is authentic and sourced through authorized distribution, the same standard we hold everywhere else on the site.
If you're not sure what gauge, tool, or ratio fits what you're doing, ask us. It's a quick question for us and it can save you a wasted spool of wire or a batch of juice that never tastes right.
Frequently Asked Questions: DIY Supplies
What is in the DIY supplies category?
Refill and storage bottles, coil building wire in multiple gauges, small tools like ceramic tweezers, and flavor concentrates or mixing components when they are in stock. What is available at any given time varies, so check current inventory rather than assuming a fixed lineup.
What is a unicorn bottle used for?
A unicorn bottle is a soft squeeze bottle with a fine tip, designed for precisely refilling tanks and pods without spilling. Vapers who buy juice in bulk often decant it into unicorn bottles for cleaner, more controlled refills, and the same bottles work well for storing homemade mixes.
What gauge coil wire should I buy?
Thinner wire, higher gauge numbers like .28 or .30, builds higher resistance coils suited to mouth to lung vaping at lower wattage. Thicker wire, lower gauge numbers like .20 or .24, builds lower resistance coils suited to sub-ohm vaping at higher wattage. Match the gauge to your device and vaping style.
What is Kanthal wire?
Kanthal is an iron-chromium-aluminum alloy widely used for vape coils because it is easy to work with, holds its shape well, and heats predictably. It is the standard wire for beginners building their first coils, and reliable enough that experienced builders still use it.
Do you sell flavor concentrates and e-liquid mixing supplies?
Sometimes, alongside the bottles and coil building supplies. Availability rotates, so check this category directly for what is currently in stock rather than assuming a fixed set of mixing ingredients is always available.
Do I need coil building tools if I use pre-built coils?
No. If your device uses pre-built replacement coils, you do not need wire or building tools. That side of this category is specifically for rebuildable atomizers, RDAs, and RTAs where you wrap and install your own coil.
Bottles, wire, tools, and sometimes the ingredients to mix your own, all in one place. Check the current listing above for what's in stock today. Everything here is authentic and shipped fast from California, and we're happy to help you figure out what you actually need for your setup.
