If items are breakable and you’re not sure that you can package the item(s) properly, you may want to visit a shipping store where they can properly pack the item(s) for you so that there is no breakage during shipment. In addition, consider paying for insurance.  Insurance will ensure that any potential damage caused during shipment is covered.

As an alternative, you can always request in the description of your item that you prefer a local buyer for pick up/drop off.  By entering your City and State when drafting your listing, buyers will be able to determine your proximity and if pick up/drop off is an option.
