Our review
Carrying a slow cooker to a potluck without the lid sliding off and dumping chilli across the car seat is a real, specific problem — and judging by how many reviewers mention seeing this on TikTok before buying, it is a popular fix. This Lantellex 3-pack of 21-inch silicone straps clips onto a cooker, pot, or bento box with a simple self-locking button and holds the lid tight, no tools needed, and at 4.5 stars from 138 ratings it is solidly liked by buyers who got it for that exact job.
Reviewers use it well beyond slow cookers too: securing a rolled-up foam exercise mat, keeping a shaker cup lid from popping open in a backpack, even as makeshift curtain tie-backs. The straps connect end-to-end, so if one is not long enough alone you link two or three together — one reviewer confirmed this worked perfectly when a single strap was too short for a wide crockpot base. It is food-grade silicone, dishwasher safe on the top rack, and the stretch holds its shape rather than going slack over time.
The one consistent gap between expectation and reality is length. Several reviewers were caught out by how short a single 21-inch strap is around a full-size slow cooker — fine for a small 3-quart crock, not enough alone for a standard 6-8 quart one. Linking two together fixes it for most people, but at least one reviewer never got a configuration that securely held a full-size cooker lid, the exact use case they bought it for.
If buying for a standard slow cooker, plan to use two straps linked together rather than one — a genuinely useful, cheap fix once sized correctly.
👍 Pros
- Self-locking button mechanism — no clips or tools needed
- Connects end-to-end for extra length on bigger pots
- Genuinely multi-purpose: crockpots, bento boxes, rolled mats, cords, curtain tie-backs
- Food-grade silicone that holds its stretch rather than going slack
- Top-rack dishwasher safe and cheap for a 3-pack
👎 Cons
- A single 21in strap is often too short for a standard 6-8 quart slow cooker
- Getting full-size coverage means linking two straps, which is not obvious upfront
- At least one reviewer could not get a secure fit for transporting a full-size cooker lid
- Does not fix a lid that was already a poor seal to begin with

FAQ
Will one strap fit around a standard 6-8 quart slow cooker?
Often not on its own — reviewers say a single 21in strap suits a small cooker, and you need to link two together for a full-size one.
Does it only work on slow cookers?
No — reviewers use it on bento boxes, rolled-up yoga or foam mats, cords, and even gazebo curtain tie-backs.
Is it heat resistant?
Yes, it is food-grade silicone rated for kitchen use and is dishwasher safe.
Will it lose its stretch over time?
Reviewers report it holds its shape well within its 2x stretch capacity, though repeatedly stretching it well beyond that is not recommended.
