What do you do when your glass pipe develops a crack? Ordinarily, you take one look at the damage and pledge to replace the pipe — especially if it is on the mouthpiece. Sometimes, though, the crack is away from the mouthpiece, and it is not big enough or sharp enough to cut. You can even find cracked glass pieces where the cracks themselves are part of the aesthetic. The latter is what we sell here, and we guarantee that it is safe.
