one of the best on the market [SEP] this is a wonderful bath brush very durable i have posted photos of exactly how thick this is compared to my last brush the bristles are soft yet durable the handle is well made thick will last as you can see from my photos my prior brush months old was really quite thin ready to crack at any moment the massage side is on a soft sponge y base so your massage is very comfortable and not overly course the wood is coated well so over time it will not cause splinters ouch my husband is and loves this the only improvement and i do mean only the handle could be longer and curved this is why i did not give this the full stars making it perfect a curved handle along with a longer one would make it easier to reach your back especially for the arthritic please note the last photo of my old brush crackedthis bath brush will not because it does not have that weird plastic base it is made of bamboo throughout except for the nice cushy base on the massage side so all in all i would recommend this durable brush
