Just started selling on Etsy, eBay, Poshmark, Depop, Amazon or TikTok Shop? Skip the guesswork of buying mailers and labels from different places. The KELVO Ship-Ready Starter Kit gives you everything to pack, label and track your first 100 orders.

What's inside

• 100 KELVO poly mailers (10" x 13") — self-sealing, tear-resistant and waterproof. Fits t-shirts, leggings, hoodies and soft goods.
• 2 rolls of 4" x 6" direct thermal labels (900 labels) — perforated and self-adhesive for USPS, UPS and FedEx. Works with Rollo, MUNBYN, Zebra and most thermal label printers. No ink needed.
• 2 rolls of 2" x 1" (also called 1x2) direct thermal labels (2,000 labels) — for barcodes, SKUs, FNSKU and inventory labels.

Why sellers love it

• Save vs. buying separately — one order instead of three.
• Right sizes, no guessing — the most-used mailer size, the standard shipping label size, and barcode labels to keep inventory organized.
• Plenty of spare labels for returns, reships and restocks.
