Quadpack showcases new airtight Jumbo Stick pen
Quadpack's Make-Up Divsion has released a new airtight version of its Jumbo Stick pen for lip or eye colour, specifically designed for long-lasting formulas to keep them from drying out.
The product's design closes off the entry points where air can flow into the pack. The base, which twists to eject the colour bullet, features a rubber O-ring. A special snap-on cap blocks air entry from the top. The two measures effectively seal the pack to create an airtight environment.
It also features a smooth swivel mechanism to prevent tilting. As a result, the colour bullet twists up and down in a straight line, preventing damage and making application easier and more comfortable.
