Shampoo Bar Travel Tins

Making leak-resistant tins for shampoo bars is a smaller business than making the bars, but it's safer.

There's a real gap here for an accessory. People who buy shampoo and conditioner bars keep asking how to store them, and there are plenty of examples of wet bars going soggy, leaking, or staining bags.

People already pay for this and you can see what tins sell for. But it's a cheap product sold in volume, so you make money on repeat buyers, gifts, and bundles, not on one big sale.

The best reason to do this: you skip cosmetic formulation and all the regulation that comes with it. The biggest risk: the tins and cases out there mostly differ in small design details, and buyers can compare them fast.

This suits a generalist ecommerce founder who can source well, test drainage and leaks, and bundle with bar makers who handle the compliance. Don't try to become a cosmetics brand.

• People do buy solid shampoo for travel. This isn't a guess.
• Buyers keep describing mushy bars, leaks, and messy bags.
• Accessories cost less than a bar-plus-accessory bundle, so you need volume.
• Selling it as housewares means you avoid cosmetic compliance.
