I ship my bubble scoops mostly in padded envelopes, well wrapped in tissue paper and bubble wrap. When I ship - whether it's a box or an envelope - I check to see if I can hear anything moving when I wiggle, shake, or smack things around. If I can hear it, I add more padding material until it doesn't. Soaps, I don't worry about because they're pretty durable, but for my scoops I make sure there's no noise. If your product is still breaking with sufficient packaging material, you do not have a robust product and may need to consider reformulating for long term durability. I don't take just shipping into consideration for products, but also if my customers will be gifting - what kind of handling does the product get then? What if my customer buys it and sticks it in a bathroom drawer where it rattles around every time they open the drawer?
