I thoroughly enjoy the Waifu product line from a design standpoint. The quality is great and the materials are awesome, but this comes at the biggest drawback: FOMO.
Being limited run/limited stock just generates an awful Fear of Missing Out aspect and ultimately means that someone who may discover a specific product down the line is SOL; the Waifu Cups x Swagger Souls line is no exception to this rule, especially with exploitative reseller markets.
As much as I enjoy these products I honestly don't know if I personally have it in me to continue purchasing them with predatory FOMO aspects.
If reruns are considered among all of the Waifu Cup designs that were One-Time-Only runs in a cyclic nature, I'd rescind the statement, as I know how merch orders can be with quantities for cos, but as it stands now this is ultimately how it is.
