Review (5/5): Great versatile little keychain bottles!
I have been using hand sanitizer bottles with built-in carabiners and sprayer bottles for rubbing alcohol, but had never looked for a spray bottle with built-in carabiners... It is great that the sprayer bottles can be attached to something, as there is less chance of dropping and losing them while travelling. Note that since the sprayer cap isn’t attached and can be still lost.
This bottle can be used for gel / cream or liquid to spray. The sprayer tube extends to the bottom of the bottle near the narrow carabiner attachment hole, so you can spray until almost the last drop. The sprayer has been working well. It is also nice that the set includes a collapsible funnel for refilling. Love them!
