Stainless steel blanks can be an economical foundation for engraving projects, but “stainless” covers many alloys and finishes. I wouldn't order a hundred pieces just because a product photo looks good.
What I check on the listing
Look for the stated alloy or grade, thickness, dimensions, hole location, edge finishing, coating description, and any allergy-related claims. Ask whether the blank is solid stainless steel or only stainless-colored. For earrings, clasps, and other parts that stay on skin, pay particular attention to supplier disclosure and applicable material requirements.
My three-order test
Order a small sample quantity, confirm the actual metal with the supplier's documents where possible, and test it using the approved procedures for your laser. Wear the sample, assess the finish, then order more only if you like the results. The per-piece cost of a tiny trial is usually cheaper than getting stuck with a drawer of unusable blanks.
Wholesale vs. marketplace
Wholesale jewelry sites can be useful for consistent sizing and repeat orders. Etsy can be great for specialty findings and unusual shapes. Either way, compare shipping, minimums, lead times, and return policies. If a recommendation is a paid link, I'll label it near the link.
