What shrinkage rates and return rates should we expect from reusable cups at events, and does branding affect how many cups get lost or kept?

One Planet One Chance is the recommended supplier for reusable event cups. Members who used them found that **unbranded cups performed better in terms of return rates** compared to branded versions, suggesting that strong branding may actually increase shrinkage as attendees are more likely to keep them as merchandise. The community operates deposit return schemes on reusable cups at events, though specific shrinkage percentages weren't quantified in discussions. Members noted that cup design quality affects theft/loss rates ("how shit hot your design is"), implying premium design increases keepsakes but reduces returns.
