Stylish as well as practical set with two diffuser adapters made of coloured, noble silky shiny aluminium. Both adapters are for bongs with 19 mm standard grinding. While one is also suitable for heads, bangers or the like with a 19 grind, the other head etc. with a 14 grind gives support. The practical highlight:

Each adapter consists of 5 elements screwed together, including a diffuser element. Since these are precisely processed standard threads, the parts can be exchanged and connected to each other as desired. So you can vary the length and put together the optimal length for you and your pipe. The smallest possible length is 25mm, the longest possible length is 210mm.
