The blue bottle with tea strainer Classic Blue Ornament is made of high-quality borosilicate glass. The glass is lead-free, odourless and tasteless and withstands sudden temperature changes (+100 degrees, - 20 degrees). The double-walled insulation ensures a comfortable temperature from the outside. You can fill it with cold drinks as well as tea. The innovative two-part filter is suitable for brewing hot tea as well as for filtering water with fruit infusion (detox water). The fruit pieces fit easily through the large bottle opening. The filter prevents the fruit from falling out when drinking. With a small handle, the strainer can be easily detached from the bottle. The fine tea filter is made of 304 stainless steel (18/8) and is more corrosion resistant than ordinary stainless steel. The ultra-fine, double-layered stainless steel filter can filter even the smallest tea granules through its very fine perforated sieve. The leak-proof screw cap with silicone seal has a practical carrying handle, so you always have everything firmly under control.
