India only uses about a quarter of the 1 billion condoms it makes every year for sex. Most of the rest are used in the manufacturing.
For example condoms are valuable to the makers of saris due to the lubrication. The condoms are placed on spools to make the thread on them run through machines faster.
In addition to being helpful in sewing the high quality of the lubricant also makes it ideal for polishing gold and silver thread.
