Just Add Water. Whack-pack strokers. Give yourself a hand! Water activated masturbation sleeves.

We chose the Just Add Water Whack Pack Sleeve because it considers the user the way good design always does — quietly, completely. Happy Ending is one of the few houses we trust to refine this category.

Sleeved in thermoplastic elastomer (tpe) — soft, body-safe, designed to be cleaned and stored properly so it lasts.

Inside, the texture is thought through — reversible. The kind of considered detail that's only obvious in use.

The Happy Ending Just Add Water Whack Pack Sleeve is a water-activated masturbation sleeve designed for discreet pleasure. Its revolutionary self-lubricating Thermoplastic Elastomer (TPE) material offers a reusable, stretchy, and soft experience. This textured and reversible stroker is ideal for solo use, providing a convenient and satisfying sensation.

Unlike traditional strokers, the Just Add Water Whack Pack Sleeve utilizes a unique, water-activated self-lubricating TPE material, eliminating the need for external lubricants. Its reversible, textured design offers varied sensations, while the included resealable bag ensures hygiene and portability for on-the-go use.

Common questions

How do I use the self-lubricating feature?

Simply add a small amount of water to the sleeve before use. The water interacts with the special Thermoplastic Elastomer (TPE) material to create a slick, smooth surface, activating its self-lubricating properties for a comfortable experience.

Is this product easy to clean?

Yes, cleaning is straightforward. After use, rinse the sleeve thoroughly with water and mild soap. The resealable bag allows for discreet storage after cleaning, ensuring hygiene and portability.

Can I use my own lubricant with this sleeve?

While the sleeve is designed to be water-activated and self-lubricating, you can use water-based lubricants if you desire additional glide. Avoid silicone-based lubricants, as they may degrade the Thermoplastic Elastomer (TPE) material over time.

The Happy Ending Just Add Water Whack Pack Sleeve offers a revolutionary, water-activated self-lubricating experience in a reusable, stretchy TPE design. Its textured, reversible nature and included storage bag make it a convenient and discreet choice for solo pleasure.
