Use alone or in a Signature Touch™ topping warmer. The 16 oz squeeze bottle (86809) is constructed of high-density plastic to withstand some heating; screw-off top has a 1 1/4" opening for filling. Be aware, warmed product inside could make bottle too hot to handle comfortably. This item number is for a single, dishwasher-safe bottle. Extra bottles are great to have on hand for quick change outs or replacements.
