Can I bring in my own leather products to shops so they can sell?

Me and my father have a lot of experience with leather And have made plenty of high quality handmade leather goods such as wallets, iphone cases, briefcases, tote bags and much more. I was wondering is it possible that I can go around nyc and walk in to shops and show them our products. See if they want to sell, we have heavy stock on all of them. But question is would they take my products and put them on their shelf? And ofcoarse a agreement would be made for commission.

There are many shops that sell products on consignment so yes it is quite possible. I would suggest that you consider selling them yourselves though for maximum profit. You can hire a company to design a website for you or place ads for free on sites such as Craig's List.

There's no law against it.
The bog chains and stores have central buyers so you would do better to approach independent shops and boutiques.
It is more professional to make an appointment with a prepared pitch than call in and expect managers to drop everything to talk to you.

Find shops that sell hand crafted works. Take samples and photos of what you make.
