The XTRM SNFFR was created by XTRM in 2019 and is manufactured in Austria, ensuring consistent quality. With its double 'two-noses,' the circulation is exceptional and clever. Benefits of the SNIFFER: - no skin contact with the contents - no skin irritation or redness on the nose or skin - the three-phase system gives 'sniffing' a whole new meaning! Care Instructions: - The SNIFFER dislikes sun, heat, cold, and detergents. - Do not leave the sniffer on the bottle permanently, as it does not prevent evaporation. - Safety note: handle with care. Do not tilt the bottle; the SNFFR by XTRM is not leak-proof. - The SNFFR does not require washing or exposure to excessive heat. Sizing: 1: Small fits small bottles and large US bottles 2: Large fits all large bottles (from the EU)
