A Paper Holder that fits inside the IKEA Kallax shelving units! You’ll have the flexibility to store your paper vertically or horizontally. The Paper Holder will provide 12 slots that will let you display your collection of cardstock and/or paper. The slots are just under 1” tall and store 12”x12” and 8.5”x11” sheets. These can also be removed for storing larger stacks. (The sturdy center slot is not removable.) Stamp-n-Storage products are handcrafted in Minnesota and made of Baltic Birch plywood. Products are delivered to you pre-assembled, sanded smooth and display ready!
