The White Rush Poppers 25ml (square) is based on the original pentyl nitrite. The angular 25ml bottle is the guarantee that in this Rush still the popular old “Reduce to the Max” Rush formula drinsteckt. All non-active ingredients are extracted in this formula according to the motto “Reduce to the Max”. This guarantees you absolute purity and an unprecedented effect. White Rush also has a small bead in the bottle. This has the consequence that the poppers remain fresh longer after opening. The bead absorbs and binds water molecules and oxygen molecules. Poppers prefer dry air to humid ambient air. So a disintegrated bead is not bad, it shows that it has served its purpose.
