Masturs - Raven Shadow Sinner - Interchangeable Sleeve

Replacement sleeve · TPE · 12.4 cm insertable depth · Diameter 2.5 cm

The Raven Shadow Sinner Interchangeable Sleeve is designed for customers who want to refresh their experience without replacing the entire unit. This is the original replacement sleeve — same dark, inviting feeling, just new TPE and a texture that's ready to deliver again. When your current sleeve has done its job and you want that 'first time' sensation back, you simply swap it out and continue.

The Inside Feeling

The sleeve features a textured internal structure that works with the base unit's functions. The pattern inside helps 'catch' vibrations and creates variation in suction intensity as you move. It's designed to make every vibration mode feel more focused, every suction pulse more present. The texture isn't aggressive — it's there to enhance what the machine is already doing, creating a layered sensation that changes as the base unit cycles through its settings.

The Material

Body-safe TPE with a soft, yielding surface. The material has enough grip to hold lubricant well without feeling tacky, and it warms quickly to body temperature. The texture is moulded into the material, not applied afterward, so it won't wear away with use. TPE is forgiving and adapts to movement, which means less friction and a more natural feel during longer sessions.

Size & Handling

Insertable depth is 12.4 cm, with a 2.5 cm internal diameter. The sleeve is designed specifically for the Raven Shadow Sinner base unit — it's not universal across different Masturs models. Installation is straightforward: remove the old sleeve, seat the new one evenly in the chamber, and you're ready. The sleeve stays in place during use and doesn't shift or rotate inside the base.

Cleaning & Maintenance

Remove the sleeve from the base before cleaning — the base unit is splash-proof, not waterproof. Rinse the sleeve under lukewarm water and wash with mild soap or toy cleaner. The textured inside requires a bit of attention: let water flow through it and use your fingers to work the soap into the grooves. Never use scrubbing pads or harsh cleaners — they'll damage the TPE surface.

Dry thoroughly with a lint-free towel, then air-dry completely before storing. TPE doesn't like being stored damp. Keep it in a cool, dark place, ideally in the original packaging or a clean pouch, and don't let it rest against other materials that might react with it.

If the sleeve becomes sticky after a few uses, that's normal for TPE. A light dusting with cornstarch or renewal powder will restore the surface. Replace the sleeve when it becomes discoloured, loses elasticity, or develops small cracks.

Lubricant

Use water-based lubricant only. Oil or silicone-based products will break down TPE and make the surface deteriorate faster. Apply generously — the textured inside works best when there's enough glide to let the pattern do its job without drag. We recommend Mshop Care Lube:IT, which is formulated to work with TPE and won't leave residue that's difficult to clean.

Keep Your Raven Sleeve Feeling Fresh

The Masturs Raven Shadow Sinner Interchangeable Sleeve is the part that does the up-close work—so a little care goes a long way. Treat it well and you’ll keep that soft, lifelike TPE feel and crisp texture that helps translate the base unit’s vibration, suction, and heat.

Before First Use

Give the sleeve a quick wash with warm water and mild, fragrance-free soap, then rinse well. Pat dry with a lint-free towel and let it fully air-dry before installing.

Cleaning After Each Session

Quick, reliable routine

• Remove the sleeve from the Raven Shadow Sinner base before washing.
• Wash inside and out with warm water + mild soap (or toy cleaner).
• Rinse until the water runs clear—leftover soap can make TPE feel tacky.
• Dry completely, inside and out, before storing.

Heads up: the base is splash-resistant, not bath/shower proof. Keep electronics out of running water.

Lubricant Compatibility

For TPE, water-based lube is your best friend. It keeps things smooth, protects the texture, and makes cleanup easier.

• Avoid oil-based lubes (they can break down TPE over time).
• If you use silicone lube, test a small spot first and wash extra well after.

Drying & Storage (Where Most Sleeves Win or Lose)

• Store in a cool, dark place—heat and sunlight speed up aging.
• Keep it away from other soft toys/materials to prevent reactions or staining.
• Don’t store it sealed while damp; let it breathe once it’s dry.

When to Replace

This sleeve is made to be swapped—because life happens. Replace it if you notice persistent stickiness, discoloration, loss of texture, cracks, or any change in feel that makes you hesitate. A fresh sleeve is the easiest “new toy” upgrade without buying the whole system again.

Fit & Handling Tips

Designed to fit the Masturs Raven Shadow Sinner base (Ø about 2 cm opening). Install it carefully, make sure it sits evenly, and never force it—your sleeve should feel snug, not stressed.
