Hi @royal123,
Welcome to the community and thank you for your post.
I understand you would like to buy items with your PayPal balance without adding a card or bank account. In the beginning, you may be able to send payments with only your balance, however, this may be stopped after a certain amount of time. In fact, every PayPal account has a sending limit that may be triggered after a while and may stop some actions. To lift the sending limit, the best thing to do is to add and confirm a card or a bank account. You can have more information on this page: How to verify my account? The cards that you can usually add to your account are prepaid, debit, and credit cards.
I hope this helps.
Chiara
