Made from 100 percent high density polyethylene, the blow-molded line represents our largest single category of products with over 50 sizes and shapes from just under a quart all the way to 60 gallons; many available in three different weights. Whether standard (Custom™) or heavy (Olympian™) weight, both are durable, flexible and easy on the budget. Side ribs and flutes give strength while a unique bottom-edge corrugation design adds further to column rigidity on many of these wide-bottomed containers. Molded-in handles on the top rim on all #5 pots (and above) insure ease of handling to the field, out of the field, during shipping and at retail. Blow-molded containers are a viable, cost-effective alternative to injection-molded pots, and, like all NSI containers, carry a one-year quality guarantee.
