High-quality sauna hourglass from SudoreWell (high-quality sauna accessories) made of solid beech wood. Easy-to-read 20 minute scale Glass cylinder with red sand. Can be seen even in dark light. Sand is a natural product. Each grain of sand is differently shaped. Therefore, it is difficult to indicate an exact run time for hourglass. Tolerances up to 2 minutes are unfortunately not to be avoided. Normally, they move under 1 minute. It may happen that several grains of sand at the passage point block each other. Simply tap lightly against the glass or turn the hourglass briefly to eliminate the blockage. Under certain climatic conditions, a light film may form on the inside of the glass cylinder. This is not a production defect, but a natural appearance due to static charge. The glass is glued with a heat-resistant special adhesive for all hourglass. This gives a significantly reduced risk of breakage. Dimensions: length approx. 32 cm. Width: approx. 5.5cm Now at a top special price!
