# Packhelp > Custom printed mailer boxes and mailing bags, designed online. - Custom packaging, Best value - Platforms: eBay, Vinted, Etsy, Depop, TikTok Shop, Whatnot - Orders a week: 0–2000 - Not yet checked by a person Suits you if you sell handmade goods or beauty products and want a printed box to open. You design it in an online editor with a 3D preview and pay in dollars on the US site. ## Who Packhelp suits If you ship your own candles or skincare, print your logo on the outside so the buyer sees it before opening the package. Pick it when every order ships in the same size of box. For mixed secondhand stock in all shapes, buy plain boxes. The eco mailer box has a low minimum order, which suits a small shop. The price per box drops on larger runs, so check the price tiers against how many orders you ship in a month. ## Eco mailer box sizes and print options The custom mailer box in the eco range is made from recyclable cardboard with FSC-certified sourcing. Choose the size from the inside dimensions of the box, measured against your product plus any padding. You design in an online editor with a 3D preview, printing on the outside, inside or both. Inside print adds to the price per box. Packhelp also sells mailing bags and plain boxes. ## Choosing one or two box sizes Measure your three most common products with their wrap, then choose one or two box sizes that leave room for paper fill. Each extra size means another stack on your shelf. Mailer boxes arrive flat. Store them flat on a shelf near your table and fold only what the day's orders need. Before you order, check the folded size against USPS and UPS dimensional weight rules. A box an inch too big can be priced on its size instead of its weight, which raises the label cost on every order. ## Branded tissue or a sticker label instead If you keep a plain mailer, add branded tissue and stickers, and compare the per-order cost with a printed box. Try a logo sticker on a plain box for a few orders before you commit to a printed run. Plain single-wall boxes in a 25 pack suit mixed or secondhand stock that needs protection but not print. ## Box cost against order value Divide the run price by the number of boxes, then add tape and fill. Set that against your average order value, and stay with plain packaging if the box costs a large share of the sale. Order a small run first to check fit and print color. If you misjudge the size on a run of 500, you pay for 500 boxes that don't fit. Reorder when your remaining boxes will last no longer than the lead time listed on packhelp.com. ## Common mistakes - Measure the product with its wrap before choosing a size. If you pick a size by eye, items rattle or get squashed. - Start with the smallest run on offer, then test fit before you order more. - A box that's larger than it needs to be can trigger dimensional weight pricing, so check carrier size rules before you order. - Inside and outside print raises cost per order. On a tight budget, print outside only until sales justify more. - Store flat boxes somewhere dry, because damp cardboard warps and the boxes no longer fold square. ## Questions ### What is Packhelp's minimum order?

The online editor shows a 3D preview of the box with your artwork. ### Are Packhelp boxes recyclable? The eco mailer box is listed as recyclable with FSC sourcing. Each product page states its own claims. ### Is a printed box worth it for secondhand stock? No, most secondhand sellers don't need one.
