Arrived in about 1 month. Carefully wrapped, I haven't tried, I hope it works. satisfied, thanks.
small size but does great work and it looks just great. don't forget to soake is 1 part chlorine en 10 parts water for 48 hours. then soake in in water+ aquarium de-colonizer for another 24 hours and rinse extremely well before putting it in aquarium. after that add a little de-chlorinizer to the aquarium water. this makes the ceramic stone just right for perfect use
