Dis eh about light bulbs but as you talking 'bout tings dat does last.
I went to Hoiarai, Guadalcanl, the Solomon Islands around March 1993.
I buy two T-Shirts and a pair of flip flops amongst other things.
The flip flops last until 2005 July. Dem tings does usuall buss in a year. I walk on roads in over 10 countries with dem tings. From TT to Canada to Turkey, Colombia, etc.
The sleevless lasted until 2010.
The other T-shirt still good and strong. I put it away a few years ago because I was travelling too much and needed to go light.
