Because all of the business units I own are required to have sophisticated First Aid stations, I have a 50+ year relationship with a supplier of those supplies. That firm ensures that every First Aid station meets the legal and insurance requirements.
The concept of Festool selling their First Aid Kit is a good idea, especially for the DIY customers.
Because only a small percentage of my Festools are kept in their Systainers at my shop, I have an extensive collection of empty Systainers stored on shelves higher than convenient to reach. My cunning plan is that because those look like brand-new, should I start to sell some of my used Festools, having the correct new Systainers will add to the value. Still, I had 9 Sys 2 Classic that are surplus. All they lacked were red latches with the white crosses.
The genuine ones Festool used on their First Aid Kits were not available as spare parts. So, I bough 3 dozen of the generic scarlet latches from a Tanos dealer, probably Japan Woodworker. Those were not expensive. The silk screen vendor used by my metal fabrication business made me a good deal adding the white crosses. We made wooden dividers for the generic Sys2s, very much as we make drawer dividers routinely. With those dividers and the decorated red latches installed, I turned the 9 wannabe First Aid kits over to my safety products vendor.
Chances are all things added together, I spend more than had I bought the Festool Kits. However, the Sys 1 was not deep enough for the cans and bottles of several products important to me. We keep 2 of our woodworking First Aid Systainers in reserve for going on site. The others are spread around my plant.
