Each suction cup a separate pressure point.

Mint green in the mid-section of the double row of suction cups. Purple at the base to the retaining ring. The color gradient is hand-injected and embedded in the platinum silicone – no print, no transfer, no abrasion. The mother-of-pearl shimmer changes with the angle of light: wet is different from dry, artificial light is different from daylight. No two specimens are identical in color – the intensity and sharpness of transitions vary slightly with each piece.\u003c\/p\u003e\u003ch2\u003e\u003cstrong\u003e100% Platinum Silicone – The Material That Makes the Vacuum Effect Possible\u003c\/strong\u003e\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e🧬 \u003cstrong\u003eElasticity with Resilience\u003c\/strong\u003e — The silicone stretches when put on and immediately returns.

With slow movements, the suction effect is clearly noticeable: the sleeve holds briefly before yielding. As the sole fixation, it is not enough – the retaining ring at the base additionally secures the fit. Both together: no slipping even with intensive use.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eHow do you put on and take off a closed-end sleeve?\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eTo put on: Fill the inner channel completely with water-based lubricant, then slide it over from the base opening. The platinum silicone stretches considerably. The slight negative pressure when putting it on is normal – it is part of the vacuum effect. To take off: Release the retaining ring, slowly peel the sleeve off from the base. Do not pull on the tip.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eCan this sleeve also be used solo without a partner?\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eYes – and the closed tip makes that possible. The object has a complete shape even without a wearer: the double row of suction cups and muscle bundles on the outside provide grip, the base opening is the entry point for solo use. The inner channel runs through the entire object up to the sealed tip.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWhat is the specific difference between this and a normal open penis sleeve?\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eAn open sleeve is a tool: It changes the surface, but the body protrudes at the end. This closed-end sleeve is a closed system: The body completely disappears, the shape of the sleeve is the only visible reaction to internal pressure. In addition: a vacuum effect that is physically impossible with open models.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eHow do you clean the closed interior – can you even reach it?\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eYes – through the base opening. Run warm water in, repeatedly squeeze and release the sleeve to flush the interior. Outside: use a soft brush over the suction cup depressions and muscle bundle interstices, air dry. For complete sterilization: boil – the closed tip withstands every boiling cycle.\u003c\/p\u003e","brand":"SilikonLust","offers":[{"title":"Default Title","offer_id":47286429614257,"sku":"SL-2229","price":67.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/0768\/5041\/files\/IMG_7594.jpg?v=1778830482","url":"https:\/\/silikonlust.de\/en\/products\/closed-end-penis-sleeve-alien-biomorph-vacuum-effect-platin-silikon","provider":"SilikonLust","version":"1.0","type":"link"}
