This is the most durable plastic box in the world.  It has a 10 year guarantee but will likely last until the sun burns out.  We created this box because the other plastic boxes out there are unsafe and very flimsy.  This box is thick black HIGH DESITY HDPE plastic and solid white VINYL, held together with STEEL BOLTS.  Other boxes with sheet vinyl walls, corrugated plastic or hdpe plastic held together only with friction slots are inferior.  This was designed and tested by experienced breeders and vets to ensure proper safety and reliability.   Includes FREE SHIPPING!  Read our feedbacks!  Everyone loves our boxes!   They are simple, affordable and by far the most durable out there.  Our boxes go to high end breeders like the US GOV and DISNEY, as well as thousands of breeders, rescues and vets in all 50 states and 14 countries.  Our whelping boxes have even been used in a major network tv show!
