Hi, We would like them made in a heavy duty Plastic as they must be able to carry weight. The thickness probably 4/5mm. The colour would be White. Dimensions are 134cm x 36cm x 68cm We would require drainage slots in the bottom to allow water to drain out and a plastic bottom to put in to make in waterproof when needed. I have attached a image of a similar design. We would want a sample sending followed by a good sized order dependant on price. Best regards, Paul Richardson
