The Black Collection XL is the largest of a family of 4 rounded and curvy BiPolar electrodes all are based on E-Stim Systems very popular Bobble but larger and with their luxurious Satin finish. The Black Collection XL is not for the faint hearted, measuring 62mm in diameter. The smooth spherical head allows it to slide in gently and the dual waisted design helps it to stay in place and also means it can either be inserted just as far as the black insulator, focusing those sensations around the opening. Or by inserting that bit further to the second waist it takes those sensations that bit deeper, delivering those tingles to the parts others don't reach. Like the majority of E-Stim Systems' Premium Electrodes the contact points are top and bottom rather than side to side, providing a more natural feeling action when the electrode moves and is suitable for both vaginal and anal stimulation. As with all E-Stim Systems Premium Electrodes the Black Collection XL is covered by E-Stim Systems Lifetime Guarantee. Size Length 163mm, Diameter 62mm Insertable Length 120mm Weight 974g Connections Fitted with 4mm connectors for use with E-Stim Systems standard 4mm cable. The wider base is ideal for E-Stim Systems Low Profile Cable and we recommend using it if you are considering longer term insertion. Cleaning Cleaning is simple and easy, The Black Collection XL can be washed off in hot water with light detergent and then wiped dry. Do NOT use caustic cleaning substances as this may damage the electrode. Make sure the electrode is fully dry including the sockets before storage. For a more thorough clean it can be disassembled and the metal parts washed separately just make sure to follow the instructions when re-assembling. Preparation We recommend the use of water based lubricant for play so as to ensure easy insertion and good conductivity. Do NOT use silicone or Hybrid lubricants. Please note condoms cannot be used with E-Stim Systems electrodes.
