The posters or self-adhesive vinyls do come with adhesive, yes. The rest, made of PVC, aluminum, or rigid materials, do not come with adhesive. They can be attached by either using double-sided tape or plastic adhesives such as silicone or similar products. In some cases, they can also be drilled with great care to avoid damaging them and fixed to the wall with screws and plugs. These attachments can be purchased on our website in the Accessories category.
