How do hotels distinguish between condoms and non-condoms?

Condoms provided by hotels usually vary according to different brands and models, but generally speaking, condoms provided by hotels are free.

In most cases, hotels will provide free condoms in room service instead of charging guests. However, if guests have special needs or require the use of a specific brand or model of condoms, they may have to pay an additional purchase fee.

It should be noted that the specific situation depends on the laws and regulations of different countries and regions. It is recommended that you consult local hotels or tourism agencies to obtain more accurate information.
