For European Customers: 

Due to new Tax regulations brought in for the EU, it will be more cost effective for EU customers to order via our Etsy shop for all orders UNDER 150 Euros as we are not IOSS registered.

These card dividers fit the 4 drawer and 12 drawer card unit and all the vertical version of the Mega Card storage boxes.

They are made of 3mm MDF.

These come in packs of 10, but if ordered with another item then the shipping is free.
