Tenga - Egg Boxy Masturbator

The Tenga Egg Boxy is a single-use egg masturbator: a soft, very stretchy sleeve packed inside a palm-sized plastic egg. Inside, small and large bumps are set at opposing angles, so strokes up and down feel different from each other. It suits anyone curious about strokers who doesn't want to clean one afterwards, and it makes a fun, low-commitment gift or travel option.

What's inside the Boxy

Every Tenga Egg has its own inner texture. Boxy's is a pattern of small and large projections arranged at opposing angles, so the downstroke and the upstroke press in different directions. That creates a shifting, slightly unpredictable feel rather than one repeating ridge. Tenga encourages you to go beyond simple strokes: twist the egg, squeeze it in different places or pull and stretch it, and the texture changes each time.

Size and stretch

Out of the case, the egg is tiny: 49 x 49 x 61 mm, about the size of a real egg, and it weighs 53 g. The TPE sleeve is so stretchy that the insertion length reaches about 190 mm and the opening widens to about 55 mm, which is why one size fits most people. The tighter you hold it, the more you'll feel the texture; a looser grip gives a softer, gentler sensation.

How to use an egg masturbator

Unwrap the egg case and open it, then take out the sachet of lotion. Apply it inside the soft egg and around the entrance. Insert yourself slowly, letting the material stretch around you. Hold and pull the egg by its base rather than the tip, which helps prevent the stretched sleeve from tearing. Add more water-based lube if it starts to drag. Once you're finished, put the used sleeve back in its case, close it and throw it away.

Single-use by design

The Egg is meant to be used once. The thin, stretched material isn't made to survive washing and repeated use, and sealing it back in its case keeps things tidy for disposal. That's the whole appeal: no cleaning, no drying, no storage. If you find you love the feel, the Tenga Egg variety packs let you try several textures, and Tenga mentions Easy Beat Standard as one to explore. For a sleeve you can wash and keep, a reusable stroker is the next step.

Solo, with a partner or as a gift

Because the egg is so small, a partner can hold and work it during foreplay, which is an easy way to bring a toy into partnered play without anything intimidating. It also travels well: the sealed case slips into a bag and needs nothing else. As a gift, a Tenga Egg is light-hearted, inexpensive and one-size-fits-most, so you don't have to guess anyone's preferences.

Lube and compatibility

A sample of water-based lotion comes in the case, enough for one session. Tenga recommends its own Egg Lotion if you want more. Any water-based lube works too, but avoid oil and silicone lubes, which can break down TPE.
