They work great! For the price.
They do not “click” shut......I traveled with these once.......I kept them in a plastic bag “just in case” they leaked.  ONE leaked very little (could have been user mistake, but....).  I use these in my shower DAILY.  They are small enough to not look messy.  They have large enough hole to make filling easy.  Love the different colors....  PERFECT size for traveling!  But I would put them in a ziplock bag for traveling to prevent any leakage onto clothing.
