One Press, Instant Switch: Open the spool with just two fingers and change refill rolls in seconds. The quick-release design keeps frequent colour and material changes simple, without a complicated spool change Swap Part-used Rolls Anytime: Secure a partly used refill with the included strap, remove it safely and fit another roll onto the same spool.

One reusable spool supports flexible colour and material changes while reducing the need for multiple empty spools
