More than a good product is needed when there are so many competitors in the market. It would help if you did something more to stand out. It would help if you had custom product packaging to differentiate yourself easily from the competition. You can keep it simple, e.g., printing thank-you notes on a custom letterhead and your logo on standard folding boxes, envelopes, or labels. If you're on a budget, you can enhance the packaging with specially colored tapes, filler material, and padded envelopes.
