Our take on the Platinum Oreoz cart
This is the richest tasting cart on our wall. Cocoa and cream sit right on top, and there’s a toasted, almost burnt-sugar note behind them.
The weight arrives in the body before the head catches up. Shoulders drop, the room gets funnier, snacks start making sense.
We save it for nights with nothing scheduled. The honest limit is right there: it’s a poor daytime cart, and two draws too many turns a plan into a couch.

Willo, the brand filling the tank
Willo is a Toronto name, and by its own telling nothing gets sourced, made or packed outside the city.
The catalog spans gummies, chocolates, pre-rolls, tinctures and a full vape range. Their filter, in their words: choose the best, pass on the rest.
This cart belongs to the 1100mg tier, the tier below their 2000mg disposable flagship.
The Platinum Oreoz flavour, and where it comes from
Refining takes cannabis oil down until little but THC is left in it. The plant’s own taste goes with it, so the flavour gets built back afterwards from terpenes.
Terpenes are the aroma compounds behind the smell of every plant, from black pepper to lemon peel. The blend in this tank is built for dessert.
- Top: dark cocoa, closer to a bourbon biscuit than milk chocolate.
- Middle: sweet cream, thick rather than airy.
- Base: roasted earth, with a burnt-sugar edge.
- Finish: long and sweet, with no fuel or citrus cutting it.
A blended profile like this one stays put. The last draw of the tank tastes like the first, and that steadiness is what distillate trades for a live-resin swing.
What a 510 thread cartridge is
A 510 cartridge is a small glass tank of cannabis oil with a coil inside and a threaded base. The number 510 describes that thread, and the thread is an industry standard.
Every cart we stock fits every 510 battery we stock. Nothing else is needed and nothing else is compatible.
- Cart: oil, coil, mouthpiece, glass tank.
- Battery: the reusable half, bought once.
- Refills: none. A spent cart gets swapped, not topped up.
- Our 510 thread vape battery covers the hardware side.
What the 1100mg number means
It’s the amount of oil in the tank, not the strength of one draw.
Our 2000mg disposables hold close to double this, sealed inside a pen. Draw for draw they hit much the same, so the bigger number buys time rather than force.
How to use this 510 cartridge
Screw it on until it stops turning easily, then leave it there.
- Voltage: 2.4-2.6V to start on any adjustable battery.
- Thick, dessert-heavy oil pulls slowly when cold — a warm hand fixes that.
- Draws: short ones, a minute apart.
- Storage: upright and indoors, never a hot car.
Chasing big clouds with high voltage burns the cocoa note off first. Low heat keeps the cookie in the cookies and cream.
Storing a dessert cart
Thicker oil moves slowly, which makes storage position matter more than it does on thin carts.
- Upright between sessions, so the oil sits over the coil.
- Room temperature, indoors, away from windows.
- A pocket beats a car console on a hot day.
Left on its side in the heat, any cart weeps a little around the mouthpiece. Standing it up solves most of that.
Cartridge or disposable pen?
Both formats hold the same kind of oil. The difference is what happens when the tank runs dry.
- Cartridge: buy a battery once, then change strains as often as you like.
- Disposable: nothing to assemble, and the whole unit retires with the oil.
- Cost shape: carts start higher and stay cheaper.
- Travel: a disposable is one item, a cart setup is two.
Vapers who stick to one flavour tend to prefer pens. Vapers who like variety end up on carts.
Who this cart suits
Evening vapers, dessert-flavour hunters, and anyone who finds sativas too busy after dark.
Newer users should take one draw and give it five minutes. Effects land within minutes and run 1-3 hours, so there’s no reason to rush a second.
EX Weed Delivery handles weed pen delivery Toronto-wide and gets to North York in two hours. There’s a $50 minimum, free delivery past $70, and an ID check at 19+ every time.
How the Platinum Oreoz cartridge compares on our shelf
Dessert flavours cluster together here. Weight is what separates them.
| Product | Potency | Type | Who it suits |
|---|---|---|---|
| Platinum Oreoz 510 cartridge (this cart) | 1100mg THC | Hybrid | The heaviest dessert flavour we carry, built for nights in. |
| Wedding Crasher 510 cartridge | 1100mg THC | Hybrid | Lighter and brighter, vanilla and grape instead of cocoa. |
| Blue Cookies 1100mg disposable | 1100mg THC | Hybrid | Cookie-sweet with berry, and no battery to charge. |
| 510 thread vape battery | Hardware only | Rechargeable base | Buy once, then swap carts as the mood moves. |
Format is the real fork in the road. A cart plus battery costs more to start and less to keep going, and it lets one setup run the whole 510 cartridges range.
Common questions
Is Platinum Oreoz indica or sativa?
Willo labels this cart a hybrid, and the effect reads body-heavy to us. The weight lands in the body first, which is why we shelve it with the night carts rather than the daytime ones.
What does Platinum Oreoz taste like?
Dark cookie and sweet cream, with a roasted, earthy note behind them. It's the richest dessert flavour on our cart wall, and low voltage keeps that cocoa edge intact.
What voltage should a THC cartridge run at?
Start at 2.4-2.6V. Thicker dessert oils want a moment to warm up, so take a short priming draw with no power before firing the first real one.
Do I need a separate battery?
Yes. This cart holds oil only and screws onto any standard 510 thread battery. Our rechargeable unit fits it, and one battery runs every cart we sell.
