High-quality sauna hourglass exclusive from SudoreWell (high-quality sauna accessories) made of solid pine wood. Easy-to-read 15 minute scale Glass cylinder with red sand. Sand is a natural product. Each grain of sand is shaped differently. Therefore, it is difficult to specify an exact running time for hourglass. Unfortunately, tolerances of up to 2 minutes cannot be avoided. Normally, however, they move under 1 minute. It may happen that several sand grains block each other at the passage point. 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 charging. On all hourglasses, the glass is glued with a heat-resistant special adhesive. This means that there is a significantly reduced risk of breakage. Dimensions: length approx. 35 cm. Width: approx. 6.5 cm. Includes rotating mounting bracket on the back with 2 holes and 2 matching screws. Now at a top special price!
