Can I buy arbitrum on Ledger?

Excuse me, could you please clarify something for me? I've been looking into purchasing Arbitrum tokens, and I've heard that Ledger hardware wallets are a secure option for storing cryptocurrencies. However, I'm unsure if I can actually buy Arbitrum directly on a Ledger device. Would you be able to shed some light on this for me? Is it possible to purchase Arbitrum on a Ledger, or do I need to go through a different platform and then transfer it to my Ledger wallet for safekeeping?
