What's safe to send without thinking about it?
Cotton t-shirts, cotton dresses, socks, underwear, casual cotton trousers, polo shirts, gym shorts, lightweight cotton button-downs, swimsuits (rinsed for sand first), bath towels, hand towels, beach towels, pyjamas, basic cotton bedsheets. These are 90% of what tourists send. They go through standard wash, dry, fold and come back fine. No special handling needed, no extra charges.
