This product is not useful for shipping. It tears too easily resulting in small strips of tape. I will not be reordering this product I may even need to replace it before it gets used.
Even though I purchased this item on sale at a decent price I use it primarily to tape light weight boxes. I'd hesitate to use it for shipping anything thru the USPS because it wouldn't stand-up or hold up to the rigorous handling. I'd still buy again but for the specific intentions to use as stated. It has its' limitations but will do well for light weight uses.
