Start with 450ml
You get a compact 450ML bottle that's easy to store and simple to pour, with enough on hand for everyday use without taking over the shelf. The liquid moves cleanly, so you're not fighting drips or waste.
Keep the refill ready
Reach for the 2.5L size when you want fewer runs back to the store. It fits well in a utility cabinet or laundry corner, and the larger volume makes sense if you go through it month after month.
Choose the 5L option
The 5L container is for the kind of routine that doesn't stop and start. Good if you're stocking for home, shared spaces, or a busy setup. Same straightforward pour, just more of it when you need the extra supply.
