Each pack contains an instruction leaflet on how to clip the frames to the boxes and our team is always ready to give any further help if needed. Each shoe storage box organiser measures Length 33 x Width 23 x Height 13.5cm, large enough to store most men’s, women’s or kid’s shoes. (Including the frames add 0.5cm to all dimensions). Inches = 13″ x 9.3″ x 5.5″. Periea clear shoe boxes are made from 0.5mm thick, durable plastic, which is also thicker than comparable boxes from rival manufacturers. The front clip-close door with outer frame and the rear air-flow frame mean that these shoe boxes keep there shape far better than a single front frame shoe box. Full stackable, vertically and horizontally, Periea shoe storage organiser boxes clip together with no effort at all and allow you to utilise spaces in your home such as under the stairs or in a wardrobe. The air-flow rear hole design keeps your footwear mould and odour free.
