The Poppers Booster Cap XTRM SNFFR Solo Small from XTRM takes the use of poppers to a new level. You unscrew the original cap from the manufacturer and screw the booster cap onto the bottle. You will quickly feel the difference. Another advantage is that the booster cap protects your skin from irritation and burns, as there is no direct skin contact with the poppers. After use, be sure to reattach the original cap from the manufacturer to prevent leakage. Try out the booster cap and write a product review. The Small size is suitable for all round 10ml and 30ml bottles from the manufacturer Lockerroom from Canada. With the red color of the sniffer, you express your preferences.
