4. Funnel
The variety in water pipes can bring about a lot of problems, especially when it comes to dab rigs. Bongs tend to have wider mouthpieces, while glass for concentrates are usually smaller and therefore have tinier holes for being filled up.
Plus, finding a space to fill up larger pieces can be a hassle and can even put your glass in harm’s way. Using a funnel to fill up your rig can turn a challenging task into a breeze.
