Appears to be a 1:1 for a Purple Confetti (11). User is reselling for 10 keys (obtained hat a few hours ago) so capping at that.

SALE #2 = 9 keys

SUMMARY

Sales: 9 / 10 keys

Sellers: 9.5 / 10 keys

The sale at 9 keys seems to have sold rather quick but given how there’s a 3+ week unsold at 10 keys and a young seller at 9.5 keys, I’d prefer to go with 9-10 and cover both sales and sellers. Especially since the 10 key seller is old. Going with 9-10 keys.
