Hi, Sorry that you are seems not satisfy with the sample. But please note that the size is small since it is just a sample for you to check the quality, and the sample price is only $1.0 which is not the price for the full size products. Regarding the thickness, if you mention the thickness of the thatch roofing, I must say that this thickness you asked is 1cm, we also have other thickness such as 2cm. If you said the strand is not thick enough, then for this stlye, it is just the thickness it have. If you want the strand thicker, we have another style which is hollow strand and the thickness is stronger than this style, the link is https://www.alibaba.com/product-detail/Factory-wholesale-recyclable-UV-resistant-waterproof_1600586560286.html?spm=a2756.order-detail-ta-ta-s.0.0.7aa52fc25DSk8R, please check and comments. Hope our explanation is clear enough. And it will be much appreciated if you consider to amend your review rating.
