Natural clay desiccant bags. Weight (approximately): 260 gr
Clay Composition: natural calcium Bentonite
The 250 gram sachets (TNT casing) are comparable to the 240 gram silica gel sachets as a dehydrating capacity.
Being a product of natural origin, the absorption capacity varies from one batch to another, therefore desiccant bags are not sold by weight but by "Dehydrating Units" (** The weight of the bags can vary by +/- 17% depending on the variability of clay performance.
The approximate dimensions of the sachets are 90 x 200 mm.

(*) The absorption capacity refers to standard conditions of 40% relative humidity with a temperature of 23° C.
Bentonite (activated clay) comes in grains enclosed in the material A sachet. Although the maximum permitted quantity of dust that can escape from the packaging is 10 mg/u.d. in accordance with DIN 55473, we do not recommend using bentonite sachets with optical equipment such as cameras, lenses, binoculars, etc. as any fine dust, even in minimal quantities, could cause abrasions on the surface of the lenses.
Bentonite sachets arrive sealed in heat-sealed plastic bags directly from the factory, so as to protect them from any contact with humid environments during transport or storage, thus avoiding providing the customer with a product that has already absorbed a percentage of humidity.
