Hollow Foot bongs are easily identifiable due to the large, hollow bottom base. Similar to a beaker, however these hollow foot bongs will tend to have a more disc shaped appearance. Hollow foot bongs are great as they keep the piece heavy at the extra low base, providing more stability and less accidents. This large reservoir on the bottom also means you'll need a good amount of water to fill it, and wont dirty as quickly. Come shop our full selection of hollow foot bongs for sale!
