I’ve tried several vegetable holders before, but the Screwcumber is by far the most reliable. It stays in place without damaging the cucumber, and I can find it again in the gravel after it’s been used. No more broken vegetables or messy cleanup.

Great product for keeping cucumbers and zucchinis in place. It’s simple, effective, and doesn’t leave any residue. I’ve used it for over three months and it still works perfectly.
James Tucker –
Works well for most vegetables, but a bit loose with very thin leaves like lettuce. Still, it’s a solid alternative to lead-based clips and much easier to manage.

Finally found a vegetable holder that doesn’t bruise the plants. The Screwcumber holds everything securely and can be reused. I’m happy with the durability and simplicity.

It’s a little small for larger fruits, but for cucumbers and zucchini, it’s perfect. I appreciate that it’s lead-free and doesn’t require special tools to install.
