SPF Tube KeySOLD OUT Get notified when its back in stock. A metal tube key to help use every last drop of your Gentle Sun Cream that also doubles as a sweet hairpin to tie back your locks. A note from Justine: Every product should have a second life, and you can use this one forever. This tube key hairpin features the Botnia logo handwritten by my daughter. We want to stop making single use products and instead create with the future in mind.
