Why us? Our monolith's unique one-way vacuum valve (1.5”) and tapered entry with quick-release tube in a metal channel (43”), ensures air-tight, sustained, quieter play. No leaky zippers or continuous vacuuming leaving your neighbours wondering why the heck you're obsessively cleaning your apartment at 2 am.
