Using custom stickers for your packages adds a personal touch.
There are many companies to choose from where you upload a logo and order custom Thank You stickers. While these stickers are great to seal packages, they are not great to hand out for networking. No one wants a thank you sticker.
I choose the more economical side and went with a versatile stamp that can have more uses.
I ordered my custom stamp from https://www.rubberstamps.com/. I make my own thank you stickers using any old name tag labels I can find at the thrift store (saving money here). I also stamp all my boxes on the outside with my stamp. This came in handy when a package accidentally made it to the Post Office with no mailing label, luckily they knew it was my package!
