Delta Xi designs for things you keep close: a notebook for working out an idea, or a case for the phone in your pocket.
The accessories use the Delta Xi mark in a quieter format than the equation-led shirts. Phone cases come in model-specific shapes, so check the exact model in your phone settings before selecting an option. Similar model names do not mean the cases are interchangeable.
A case’s charging compatibility and materials are described on its product page. MagSafe-compatible and standard cases are separate products. The notebook is a hardcover, lined format; check its availability rather than assuming an out-of-stock item can ship immediately.
Accessories are fulfilled through Printful and may ship separately from apparel. Some products have destination restrictions, which affect what can be ordered. Standard shipping is included to supported destinations, while customs charges can still apply. For gifts, use the recipient’s shipping address at checkout and check the delivery estimate first. Contact support before ordering if a particular material, measurement or delivery date is important to you.
