The Boutiq Switch V4 Bubblegum Runtz x Rainbow Beltz puts two candy leaning tanks in one two gram device without letting either lose its shape. Inside a Boutiq Switch V4 Bubblegum Runtz x Rainbow Beltz the chambers stay sealed separately and are picked by a mechanical switch.
Bubblegum Runtz beside Rainbow Belts is the sweetest V4 we stock, and it is completely unapologetic about it. Both tanks are confectionery, both are soft, and neither offers any relief from the other. This is a device for people who already know they have a sweet tooth.
What is in each tank

Bubblegum Runtz
The first tank holds Bubblegum Runtz, a indica-leaning profile. Bubblegum Runtz is the most straightforwardly nostalgic flavor we carry, pink bubblegum with the Runtz family’s fruity backbone holding it together. There is no complexity to hunt for and that is the point. It is sweet, soft and immediately recognizable from the first draw.
Rainbow Belts
The second tank holds Rainbow Belts, a indica-leaning profile. Rainbow Belts leads with the sour sugar coating of the sweet it is named after, then settles into something softer and creamier underneath. The sour note is the first thing you taste and the first thing to fade, which makes the opening draw the most vivid one. It sits at the indulgent end of the candy family and works best when you are not trying to concentrate on anything.
Running the two tanks together
The honest assessment is that these two are close relatives. Bubblegum Runtz is pink gum over a fruity base; Rainbow Belts is sour sugar over something creamier. The difference is real but narrow, and after a long session the palate stops distinguishing them. That is not a fault so much as a consequence of the pairing, and the way to work with it is to treat this as a single-flavor device with a mood switch rather than as two options. Rainbow Belts is the slightly more complex of the two and worth saving for when you are paying attention.
Two candy tanks, and why the Boutiq Switch V4 Bubblegum Runtz x Rainbow Beltz still works
Pairing two sweet profiles sounds redundant until you use them. Bubblegum Runtz is rounder and creamier while Rainbow Beltz is sharper and more sour, so the Boutiq Switch V4 Bubblegum Runtz x Rainbow Beltz gives you two different kinds of sweet rather than the same one twice.

Who this one suits
Buy this if candy profiles are simply what you like and you have no interest in contrast. It is genuinely enjoyable on those terms. Do not buy it expecting variety, and do not buy it if you tire of sweetness quickly, because there is nowhere to go within this device.
Storage, pacing and how it ages
Candy profiles are heat-sensitive at the top and durable underneath, so both tanks keep their sugar and lose their definition. Rainbow Belts suffers more, since its sour opening note is exactly the sort of thing that fades first, and without it the tank moves closer to Bubblegum Runtz. Late in this device’s life the two halves converge noticeably. Use the belts side early while the distinction still holds.

Bubblegum Runtz and Rainbow Beltz, honest answers
Two candy indicas. Will I get bored of it?
You might, and it is worth being straight about that. This is the sweetest pairing in the V4 line and there is no savory or fuel note anywhere in it to reset your palate. What saves it is that Bubblegum Runtz is a single flavor, soft and pink and rounded, while Rainbow Beltz is a mixed sour candy with an acidic edge. The sour side does the resetting that a fuel tank would do elsewhere.
Which is heavier at the end of the night?
Both lean indica, so neither is a daytime tank, but Bubblegum Runtz settles a little more softly. Rainbow Beltz has enough sour lift at the front to feel briefly brighter before it goes the same way. If you are choosing a tank purely to end the evening on, the bubblegum side is the more reliable of the two and it is less likely to leave you reaching for one more draw.
Is there any sour bite to Rainbow Beltz or is it just sweet?
There is a genuine tartness at the front of the draw, the sort you get from the sugar dusting on a sour belt rather than from citrus. It fades quickly into the sweetness underneath, but it is present enough to be the reason this tank exists next to a bubblegum.
Should I buy this if I dislike sweet flavors?
No. There is no version of this device that will suit you, and there are pairings elsewhere in the V4 range built around fuel, pine and citrus that will. We would rather point you at those than take the sale and have you regret it. Nothing about this device improves for someone who wanted a fuel profile.
What comes for the price?
At $25, the price on this listing at the time of writing, you get the finished device rather than a component. Two sealed chambers, 2g of extract between them, a mechanical selector and a USB-C rechargeable battery, all in one shell with nothing to assemble.
Does the sweetness make the coil gum up faster?
Not in the way people assume. The coil is matched at the factory to the viscosity of the extract, and sweetness in a live extract is a terpene profile rather than added sugar, so there is nothing in there to caramelize. Long hard pulls will still flood it, which is a separate problem with a separate fix.
Candy profiles turn cloying if the device gets warm, so keep the Boutiq Switch V4 Bubblegum Runtz x Rainbow Beltz somewhere cool and upright. Charging it in short sessions rather than draining it flat keeps the last of both tanks tasting like the first.
Adults 21 and over only, which we check rather than assume. When the parcel arrives, take thirty seconds to run the carton code through the verification tool. If you want to know when it is likely to arrive, that is covered on the shipping page.
