This treatment brings a bit of gravitas to a cute or kitschy array. Create a diorama with the hierarchy of your choice (the order here: dogs and cats on top, farm and wild animals in the middle, mollusks and tall, quirky characters below). If you own more tchotchkes than the case can contain, rotate stock when the mood hits, keeping the overflow in divided ornament boxes. Clean the case with a microfiber glass cloth; the contents will be well protected from dust. Antique display cabinet, Paula Rubenstein Ltd., 212-966-8954.
