Stickerbrand was extremely prompt in responding to my e-mail inquiries prior to purchase and alleviated my concerns about installation by supplying a helpful video link to show me how to install a large, multi-piece decal. Shipment arrived on time and I installed the decal successfully. The only reason I don't give a 5-star rating is because it wasn't clear to me that black could be ordered in a matte option...I am not happy with the shiny black. More my own oversight when looking at the colour options, but it might be nice for Stickerbrand to have some sort of pop-up alert when customers pick black to confirm whether they want shiny or matte. I am now planning to order more decals for the same room, but am now torn whether to continue in the shiny black or switch to matte. Decisions, decisions...!
