Learn how to use a tube key to squeeze out every last bit of toothpaste, moisturizer, or cosmetic. Simple steps and common mistakes to avoid.

Quick answer

Slide the slit of the tube key over the flattened end of your tube, then roll the key upward toward the cap as you use the product. This simple tool keeps the tube tightly wound and pushes every last bit of product toward the opening.

Why a tube key works better than squeezing by hand

Hand-squeezing a tube often pushes product back and forth, leaving a messy, crumpled tube and plenty of product stuck near the crimp. A tube key applies even pressure as you roll, so the contents move steadily toward the cap. It also keeps the tube neat and upright, which is handy for small bathroom shelves. The key is especially useful for thick formulas like toothpaste, hand cream, or ointments that don’t flow easily on their own.

When a tube key isn’t the right tool

Tube keys are designed for standard plastic or laminate tubes with a crimped end. They don’t work well on rigid metal tubes that crease permanently, or on tubes with a wide, flat crimp that won’t fit the key’s slit. If your tube has a pump or a hard plastic body, a key won’t help. Also, if the product has separated or dried out, rolling won’t fix the texture—only proper storage will.

How to use a tube key, step by step

Flatten the tube end: Start with a tube that’s been used enough to have some empty space at the crimped end. Smooth the end flat with your fingers so the key can grip it evenly. Don’t try to attach the key to a brand-new, full tube—there’s no room to roll.
Slide the key onto the crimp: Hold the tube key with the slit facing the crimped end. Push the slit over the very edge of the tube, making sure the key sits straight across the width. If the key won’t slide on, check that you’re using the crimped end, not the cap end.
Roll upward toward the cap: Twist the key upward in small increments, pressing the tube flat as you go. Stop when you feel resistance—the product is now pushed forward. Don’t over-roll in one go; rolling too fast can force product out unexpectedly.
Use product as normal: Squeeze or dispense from the cap end. As the tube empties, roll the key a little further to keep the product near the opening. Keep the key in place between uses to maintain pressure and prevent the tube from unrolling.
Store upright and repeat: Stand the tube on its cap or store it flat with the key in place. Each time you need more product, give the key another small turn. Avoid leaving the tube in direct heat, which can make thin formulas leak past the key.
