I'm interested in customizing a fabric box that meets specific requirements. The design should feature Velcro strips on all four top edges and include removable reinforcement strips on the side panels for maintaining its shape. It also needs to be flexible enough for easy insertion and removal from an outer container without compromising its structure. For the fabric color, please provide options in black or dark grey for a sleek look. I'm keen on receiving a sample before proceeding with the order, and I would like to know the associated costs for shipping to the Netherlands. The dimensions are Width: 39 mm, Depth: 300 mm, Height: 800 mm.
