The model has real world scale and measures 5.6 cm in width, 7.1 cm in length and 11.9 cm in height. The mesh of the lid and the mesh of the actual jar are not connected in Edit Mode, so they can easily be selected and moved individually.
All used textures and maps are included: one texture / diffuse map and one glossy map (invert for roughness). Each image measures 4096 x 4096 px. UVs are unwrapped and everything is named logically.
