laser blanks suppliers

[Craftify]

Hi everyone, me and my wife purchased a laser engraver few months ago and business is picking up.
We struggling to find a good supplier for blanks (pens, key chains, chopping boards, tumblers, promotional gadgets etc..)
We have been using Temu but the problem is the continuity, often items sell out so if customer wants to order more the item is usually out of stock or not sold anymore. I was wondering if someone can recommend a supplier with reasonable prices (enough to make a margin on them) that has constant stock .
Ideally someone that can also supply a catalogue and don't require orders of 1.000.000 units each time.
We are located in Western Australia.

Thank you very much in advance
