Model: BTL-025a Shipping Weight: 0.01lbs Pump your lotion from the bottle with unit. Please note that these pumps are sized to fit the liter bottles in our brand line. Lid sizes are not universal so we can not guarantee that your liter bottle is the same lid size as ours. We have also been moving to a new cap on our liter bottles so please select the pump to fit the bottle you have. Fortunately they are different colors so it makes it easy to tell them apart.
