These cardboard bins fit in our 4 Cubby and 6 Cubby Inserts for Kallax, Better Homes and Gardens and Thresholds. They are made of 200 lb. test corrugated cardboard (meaning very strong and durable) and are white on the outside. Very easy to assemble - no tape or staples needed - watch the video below to see how they are assembled.
All measurements are approximate. Any items other than the product described shown in the pictures is not included (scissors, yarn, measuring tape, yarn needle, crochet hook, knitting needles, etc.). All of my handmade items are made in a smoke free environment. My home is dog friendly but my little one does not come in contact with any of my handmade items or supplies.
