Whether you sell on ebay, Mercari, or Poshmark, shipping supplies are a must. You do not want to be scrambling at the last minute for ink or tape. Do your best to keep costs at a minimum right from the start. As you get busier and more comfortable with the shipping process, you may choose to do some upgrades. Personal thank you cards, business cards, cute polymailers or even a lighting kit will be nice additions. For now, save yourself some money and stick to the basics.
Printer or thermal label printer
Paper or labels
Boxes (priority mail boxes are free from USPS) or any recycled brown boxes
Polymailers for 1st class packages
Scale Poshmark limit is 5lbs, 1st class is under 16oz
Camera or phone camera I use my iphone camera
Plain tissue Color tissue is pretty, but color can run onto items (unless item gets bagged 1st) I buy this in bulk 5200 roll, lasts about 8months
Clear bags I place items in clear bags and seal with a thank you sticker
This is a basic list of supplies to get started with. This is not a must-have list that you need to go out and purchase. Many of these items you may already have somewhere in your home. Gather them up and make yourself a designated ‘shipping’ area. Packaging your items will be less stressful if you have an organized area do so.
