Shisha charcoal assigned to 20 mm
The 20 mm selection covers flat charcoal formats. For Rects20 the size stands for the height; base area, pack quantity and shape must also be compared.
We currently carry only a few items for Diameter 20 mm. The full Hookah charcoal range is available in the category.
The size of twenty millimetres denotes the height of the cuboid for Rects20. Its base area is larger and is stated separately. Although the attribute is called diameter in the filter, these are not round charcoal tablets of that diameter. For the space on a bowl, all dimensions of the piece count.
So first distinguish between a cube and a flatter rectangular format. Only then do you compare the pack size on offer. A kilogram contains a different assortment depending on piece format; the weight does not imply a fixed piece count for all brands. The right arrangement in the HMD is likewise not explained by the short dimension alone. It depends on the intended bowl. The page helps you find this size assignment without equating different shapes or promising a fixed burn time per bowl.
