XTRM SNFFR, the ultimate booster for all fans. Screw it on and the hottest boom is here. The XTRM SNFFR was designed by XTRM in 2019, and they produce them themselves in Austria, guaranteeing consistent quality.Ready for the next level with the Double XTRM Sniffer 2.0? With the XTRM Double Sniffer you can screw two small bottles onto it at the same time (only small bottles fit). The booster effect is increased many times over, and you have no contact with the aroma, meaning no unpleasant skin contact and no irritation or redness. Simply unscrew the lid of your bottle (bottle not included) and screw the XTRM Sniffer onto it. Thanks to a system registered with the German Patent Office, the 3-hole design ensures a dreamlike circulation for the best kick.Please do not leave the sniffer on the bottle permanently, as it is not leak-proof, does not prevent evaporation and does not prevent leakage if the bottle tips over. Do not expose it to high heat or cold.The perfectly developed channel system gives the aroma a dreamlike circulation, massively reinforcing the effect for an unprecedented and significantly improved handling of your favourite head cleaner.
