What should I check before buying svg files for laser cutting for commercial use? ?

Hi everyone! I’m planning to buy svg files for laser cutting here https://lasersvgtemplates.com/ for commercial projects. The site says the files can be used commercially, which is important for my business. Before purchasing, I wanted to ask — what should I check first to make sure the files are suitable for selling finished products? Also, has anyone here already bought from this site, and how was your experience with the purchase and file quality? Just trying to make sure everything is smooth before I start using the designs in products I plan to sell.
