The rubber lining is made to improve grip on the lid, and the surface indentations help reduce slipping between your hand and the tool. It’s slim enough to store in a drawer or hang on a hook for quick access.
Tip: Both sides can be used to match different lid sizes. For larger lids (no more than 3 inches), the brand recommends using the third “opener ring” instead of the fourth.
- 6-in-1 opener with multiple circular openings for small to medium lids (1–3 inches) plus hooks to help release airtight large lids
- Long handle adds leverage; rubber lining helps provide a firm grip
- Surface indentations create a more secure, non-slip hold between your hand and the opener
- Compact, slim design stores easily in a drawer or hangs on hooks
- Plastic construction with easy-to-clean rubber lining
Note: It may still require some grip strength to hold the lid securely; otherwise, it can slip.
