Sorry I'm just now getting to your question, I don't Ebay, but I like to read up on what's goin on & try to help out when I can.
Anyways, I'm pretty sure you could guess the weight. Before I got an actual postal scale, I used a regular bathroom scale to est. the weight of my packages. It won't give you the accurate weight, but close to it.
I highly recommend getting a scale. I'd die without mine! I often would underestimate & lose out on lots of money that I couldn't afford to lose. OR I'd overestimate & feel bad,offer a refund but most the time they'd refuse the refund due to too much trouble.
Good Luck Selling
