Our review
Regular rigid funnels take up disproportionate drawer space for something you use a few times a month. These KongNai silicone funnels collapse flat — all four stacked take up less room than a single conventional funnel. That one trick is why 10,000+ people buy them every month.
The set includes two sizes: large (4.3 inch diameter) for pouring into bottles, jars, and coffee-maker reservoirs, and small (2.8 inch) for narrow-neck bottles and spice containers. Food-grade silicone is heat-resistant to 250°C, BPA-free, and dishwasher safe. The four bright colours (red, orange, blue, green) make them easy to spot in a drawer — a small but genuinely useful design choice.
Reviewers use them well beyond the kitchen: filling resin printers, topping up car fluids, transferring charcoal and desiccants, and even as emergency camping gear. The silicone is thick enough to hold its shape when extended but flexible enough to fold completely flat with one pinch. Multiple owners report years of use with no degradation.
Two caveats worth knowing. First, silicone conducts heat — if you pour boiling liquid through the funnel, the material gets hot and can be difficult to hold. Let liquids cool slightly or use gloves. Second, the silicone surface creates friction with dry powders, which can cause them to stick rather than flow through. These funnels work best with liquids and thin fluids. For dry ingredients, a stainless-steel funnel is a better choice.

FAQ
Do they hold their shape when pouring?
Yes — the silicone is thick enough to stay open when extended. They hold position on bottle necks well. But they are flexible, not rigid — very heavy flows can cause slight deformation.
Can I use them for dry ingredients?
Liquids work best. Dry powders can stick to the silicone surface due to friction. For spices, flour, or fine powders, a stainless-steel funnel flows more freely.
Are they safe for hot liquids?
The silicone is heat-rated to 250°C, so the material is safe. However, it conducts heat — pouring boiling water makes the funnel hot to hold. Let liquids cool slightly first.
How small do they fold?
The large folds to about 0.6 inches thick, the small to 0.4 inches. All four stacked are thinner than a single rigid funnel.
