If you are looking to buy a custom sized acrylic display case with a modern base or a flat base then these are limited by the fact that they are made from 3mm acrylic. You can change to a wooden base display case instead, which gives much bigger sizes as they can be made from 5mm thick acrylic, as well as 3mm acrylic. If you are already on the wooden base display case page and it says it is too big to make, or you really want one of the 3mm thick display cases made in the bigger size, then contact us, we may still be able to make it.
